Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art.
Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the disclosed aspects may be practiced without one or more of the specific details, or with other methods, components, devices, steps, etc. In other instances, well-known methods, devices, implementations, or operations are not shown or described in detail to avoid obscuring aspects of the disclosure.
Moreover, the drawings are only schematic illustrations and are not necessarily drawn to scale. The block diagrams depicted in the figures are merely functional entities and do not necessarily correspond to physically separate entities. That is, the functional entities may be implemented in software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
Impeller machines are typically comprised of an impeller, blades, and a bladed disk. The impeller is the rotating part of the impeller machine, and the impeller is an annular structure fixed to the impeller. During rotation of the impeller, liquid or gas passes through the blades and is subjected to the force of the blades to change momentum. The blades transform the momentum of the liquid or gas into a force and move along their curved surfaces, ultimately converging onto a disk. Therefore, the blades of the impeller and the impeller disc are closely related, and the blades of the impeller are matched with the impeller disc in a specified mode so as to ensure that the flow direction and the rotation direction of fluid are consistent, and ensure that the impeller machinery can work normally. Meanwhile, the impeller disc plays an important supporting role in rotation and stability of the impeller, and the end faces of the blades are usually placed on the impeller disc.
Fig. 1 shows a schematic diagram of a system architecture of an exemplary application environment to which a disk model generation method and apparatus of an embodiment of the present disclosure may be applied.
As shown in fig. 1, the system architecture 100 may include one or more of a desktop computer 101, a portable computer 102, a smart phone 103, and other terminal devices, a network 104, and a server 105. The network 104 is the medium used to provide communication links between the terminal devices and the server 105. The network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, among others. The terminal device may be various electronic devices with data processing functions, and the electronic device has a display screen thereon, where the display screen is used to display the target structural feature points or the leaf disk model to the user, including, but not limited to, a desktop computer, a portable computer, a smart phone, and the like. It should be understood that the number of terminal devices, networks and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation. For example, the server 105 may be a server cluster formed by a plurality of servers.
The method for generating the disk model provided by the embodiment of the disclosure can be generally executed by a terminal device, and correspondingly, a She Panmo type generating device is generally arranged in the terminal device. However, it will be readily understood by those skilled in the art that the method for generating a disk model according to the embodiment of the present disclosure may be performed by the server 105, and accordingly, the She Panmo type generating device may be provided in the server 105, which is not particularly limited in the present exemplary embodiment.
Further, it should be understood that the She Panmo type generation method of the embodiments of the present disclosure may be configured as a software module. In some implementation scenarios, the blade disc model generation schemes of the present disclosure may be deployed separately to implement the build generation of blade disc models corresponding to different types of blade models. In other implementation scenarios, the blade model generation scheme of the present disclosure may be deployed in other software, as a functional module of the software, for example, in analysis software of the turbomachine, and the application mode of the She Panmo type generation method is not particularly limited.
In the construction scheme of the related integrated leaf disc or the integral leaf disc, software such as a mechanical three-dimensional design tool and the like is mainly adopted to carry out two-dimensional or three-dimensional design through man-machine interaction, and a designer carries out the processes of data processing and feature generation step by step manually.
In a two-dimensional design scheme, the construction process of the leaf disc model mainly comprises the following steps: setting a reference model and size, drawing the outline of a disk body of the blade disk, turning the outline into a disk entity, drawing the bottom and back curves of the blade basin, drawing the front edge and the back edge, splicing the blade edge heads, drawing all section lines, stretching the section lines to generate a solid part of the blade, extending the intersection of the blade and the disk entity, cutting redundant parts, copying, arranging the blade, designing a rounding angle, and punching. The design method must be designed in sequence strictly according to the flow, and because a great number of dimension parameters are required to be input for constructing the leaf disc body, the constraint is more, the modeling is time-consuming and labor-consuming, the process involving the leaf in the middle has a great number of repeated drawing and repeated splicing works, and the construction efficiency of the leaf disc model is lower.
In a three-dimensional design scheme, parameterization and region division are respectively carried out by analyzing the regular shape (such as an inner ring part and an outer ring part) and the curved surface shape (a blade part) on the blade disc, a characteristic model of the blade disc is established, the design is carried out based on the characteristic model, and a part of repeated work is simplified. However, when the specification and morphology of the product change, a complete redesign flow is still needed, and the blisk designed on the basis of the method is further subjected to fine adjustment according to the processing technology, quality and the like of the actual working condition, so that the design period of each product is long, and the operation is complex, so that the software use proficiency of a designer is also very high.
Based on one or more problems existing in the related art, in the present exemplary embodiment, a leaf disc model generation method is provided first, and a terminal device is used to execute the method as an example, and a She Panmo type generation method in the embodiments of the present disclosure is described in detail below. Fig. 2 schematically illustrates a flow diagram of a disk model generation method according to some embodiments of the present disclosure. Referring to fig. 2, the disk model generation method may include the steps of:
Step S210, obtaining blade basic data corresponding to a pre-constructed blade model;
step S220, determining target structure feature points according to the blade basic data;
and step S230, generating a leaf disk model matched with the leaf disk model based on the target structural feature points.
According to the She Panmo type generating method in the present exemplary embodiment, blade basic data corresponding to a pre-constructed blade model may be obtained, then target structural feature points may be determined according to the blade basic data, and further a blade disc model matched with the blade model may be generated based on the target structural feature points. On the one hand, target structural feature points can be directly generated according to input blade basic data, and then a leaf disc model can be generated according to the target structural feature points, so that the proportion of manual participation in the construction process of the leaf disc model is effectively reduced, and the construction flow of the leaf disc model is shortened; on the other hand, when the design of the blade model changes, the integral blade disc model does not need to be readjusted, the target structural feature points corresponding to the blade disc model can be directly adjusted, the workload required by She Panmo type adjustment is effectively reduced, and the construction efficiency of the blade disc model is further improved.
Next, a She Panmo type generating method in the present exemplary embodiment will be further described.
In step S210, blade base data corresponding to the pre-constructed blade model is acquired.
In an exemplary embodiment, the pre-constructed blade model refers to a blade model which is constructed in advance by design software, and the blade model has a simpler structure compared with She Panmo type, so that the blade model can be directly constructed manually.
The blade basic data refers to relevant basic parameters corresponding to the blade model, for example, the blade basic data can be data of a suction surface, a pressure surface, a front edge, a rear edge and the like of the blade; of course, the blade base data may also be coordinates of a blade endpoint corresponding to the blade model after the blade model is placed in a preset coordinate system, for example, the blade base data may be coordinates corresponding to a bottom endpoint of the blade model in a Z direction and an R direction of the meridian plane coordinate, and the type of the blade base data is not limited in this example embodiment.
After the pre-constructed blade model is obtained, a corresponding input interface is provided, and the user inputs blade basic data through the input interface and the blade model, for example, the user can select the bottom end point of the blade through an input window in a prompting mode, so that the bottom end point coordinate of the blade model is obtained; of course, after the blade model is obtained, the blade model may be automatically analyzed by accessing a corresponding blade model analysis interface to obtain the blade basic data corresponding to the blade model, and the mode of obtaining the blade basic data corresponding to the blade model in this example embodiment is not limited in particular.
In step S220, a target structural feature point is determined from the blade base data.
In an example embodiment, the target structural feature points refer to key points for characterizing the shape structural feature of the leaf disc model, for example, the target structural feature points may be key points for characterizing a two-dimensional graph of She Panmo type on a meridian plane, or may also be key points corresponding to the outline of the leaf disc model under three views, and of course, in some scenes, the target structural feature points may also be three-dimensional structural key points corresponding to the leaf disc model for characterizing the minimum circulation unit, and the selection of the target structural feature points is not particularly limited in this example embodiment.
The target structural feature points required by the construction of the leaf disc model can be automatically determined according to the leaf base data, for example, the leaf base data can comprise coordinates corresponding to the bottom end points of the leaf model in the Z direction and the R direction of meridian plane coordinates respectively, namely, the leaf base data can be coordinates corresponding to the bottom end points of the leaf model on the meridian plane, and then the key points, namely, the target structural feature points, on the two-dimensional contour graph corresponding to the leaf disc model on the meridian plane can be determined based on the bottom end point coordinates of the leaf model on the meridian plane; of course, if the blade basic data may be the bottom end point coordinates corresponding to the blade model under the three views respectively, then the key points on the two-dimensional contour graph corresponding to the blade disk model under the three views respectively, namely the target structure feature points, may be determined based on the bottom end point coordinates corresponding to the blade model under the three views respectively.
In step S230, a blisk model to which the blisk model matches is generated based on the target structural feature points.
In an example embodiment, after obtaining the target structural feature points, a three-dimensional leaf disc model may be constructed through the target structural feature points, for example, taking the two-dimensional structural feature points of the leaf disc model, which is pre-generated, on a meridian plane as an example, the target structural feature points may be first connected to obtain a two-dimensional structure diagram corresponding to the leaf disc model on the meridian plane, and then three-dimensional modeling may be performed through the two-dimensional structure diagram, for example, a leaf disc model matched with the leaf disc model may be directly generated according to the two-dimensional structure diagram through an OCC (OpenCasCade, geometric modeling platform) tool.
The target structural feature points are directly generated through the input blade basic data, so that a blade disc model can be generated according to the target structural feature points, the proportion of manual participation in the construction process of the blade disc model is effectively reduced, and the construction flow of the blade disc model is shortened; on the other hand, when the design of the blade model changes, the integral blade disc model does not need to be readjusted, the target structural feature points corresponding to the blade disc model can be directly adjusted, the workload required by She Panmo type adjustment is effectively reduced, and the construction efficiency of the blade disc model is further improved.
The following describes step S210 to step S230 in detail.
In an exemplary embodiment, the blade base data may include a blade endpoint coordinate, where the blade endpoint coordinate may be a coordinate corresponding to a blade top endpoint or a coordinate corresponding to a blade bottom endpoint, and the exemplary embodiment is not limited thereto. For ease of understanding and description, the following description will take the coordinates of the end points of the blade as the coordinates corresponding to the end points of the bottom end of the blade as an example.
Specifically, the determining the target structural feature point according to the blade basic data may be implemented through the steps in fig. 3, and referring to fig. 3, the method specifically may include:
step S310, determining a blade reference position of the blade model on a meridian plane according to the blade endpoint coordinates;
step S320, determining leaf disc process parameters of a pre-generated leaf disc model on the meridian plane according to the leaf end point coordinates;
and step S330, determining the She Panmo type target structural feature points on the corresponding meridian plane based on the blade endpoint coordinates, the blade reference positions and the blade disc process parameters.
The blade reference position refers to data for determining a position of the blade model in the current coordinate system, for example, the blade reference position may be a center line corresponding to the blade model determined according to a blade endpoint coordinate, for example, the blade endpoint coordinate may be a coordinate of a bottom end endpoint of the blade model in a Z direction and an R direction of a meridian plane coordinate, a coordinate value corresponding to the center line of the blade model in the Z direction may be calculated by a coordinate value in the Z direction in at least two blade endpoint coordinates, and a coordinate value corresponding to the center line of the blade model in the R direction may be calculated by a coordinate value in the R direction in at least two blade endpoint coordinates, and a coordinate value corresponding to the center line of the blade model in the Z direction and a coordinate value corresponding to the center line in the R direction may be taken as the blade reference position of the blade model. Of course, the blade reference position may also be the length of the bottom end face of the blade model, i.e. the blade rim plate length, and the present exemplary embodiment is not particularly limited as to the type of data characterizing the reference position of the blade model.
Because the bottom end surface of the blade model is required to be combined with the blade disc model, the accuracy of the determined She Panmo type corresponding target structural feature point can be effectively improved by determining the reference position of the blade.
The blade disc process parameters refer to relevant parameters required when the blade and the blade disc can be accurately combined in the actual manufacturing process, for example, the blade disc process parameters can be error offset, flange length proportionality coefficients, and proportionality factors of the blade disc model in different directions, and the type of the blade disc process parameters is not particularly limited in the embodiment.
The target structure characteristic points are generated by combining the technological parameters of the leaf disc, the accuracy of the determined She Panmo type corresponding target structure characteristic points can be further improved, the follow-up process of adjusting the leaf disc model in a manual mode can be effectively avoided, and the construction efficiency of the leaf disc model is further improved.
After the blade reference position and the blade technological parameters are determined, the target structural feature points of the blade model on the corresponding meridian plane can be determined through the blade endpoint coordinates, the blade reference position and the blade technological parameters, the generating efficiency of the target structural feature points can be effectively improved, the accuracy and the effectiveness of the generated target structural feature points can be ensured, and the accuracy of the subsequently generated blade model is further ensured.
Optionally, the blade endpoint coordinates include first endpoint coordinates in the first direction, for example, the first direction may be a Z direction, the first endpoint coordinates may be coordinate values corresponding to the bottom end endpoint of the blade in the Z direction, and accordingly, the blade process parameters may include first scale factors in the first direction, where the first scale factors refer to relevant scale factors for generating coordinate values of the target structural feature points in the Z direction, for example, the first scale factors may be 0.3 or 0.2, and may be specifically determined according to an actual application scenario, and this embodiment is not limited in particular.
Specifically, a first feature point coordinate of the structural feature point in the first direction may be determined according to the first endpoint coordinate, the first scale factor, the blade reference position, and the blade disk process parameter.

After obtaining the blade reference positions Zmean, rmean, and Δz, and the blade technological parameters L and L from the blade end point coordinates, the target structural feature points 1 to 12 of the blade model on the corresponding meridian plane can be determined based on the blade end point coordinates a (Za, ra) and b (Zb, rb), the blade reference positions, and the blade technological parameters.
Specifically, the coordinates of the target structural feature point in the Z direction may be determined from the end point coordinates of the blade end point coordinates in the Z direction, and for example, the coordinate values of the target structural feature point in the Z direction may be determined from the relational expression (6) to the relational expression (11):
Z[1] = Z[2]= Z[5] = Z[6]= Za – l （6）
Z[7] = Z[8]= Z[11] = Z[12]= Za - l + L （7）
Z[3] = zMean - ((zMean - Z[1])×A) （8）

Specifically, the coordinates of the target structural feature point in the R direction may be determined from the end point coordinates of the blade end point coordinates in the R direction, and for example, the coordinate values of the target structural feature point in the R direction may be determined from the relational expression (12) to the relational expression (18):
R[1]=R[7]=Rmean×C （12）
R[2]=R[3]=R[8]=R[9]=Rmean×D （13）
R[4]=R[5]=Ra×F （14）
R[10]=R[11]=Rb×F （15）
K=(Zb-Za)/(Rb-Ra)=(Za-Z[6])/(Ra-R[6])=(Z[12]-Zb)/(R[12]-Rb) （16）
R[6]=(Za-Z[6])×(Rb-Ra)/(Zb-Za)（17）
R[12]=(Z[12]-Zb)×(Rb-Ra)/(Zb-Za)（18）
wherein R1-R12 can respectively represent coordinate values of the target structural feature points 1-12 in the R direction, C, D and F can represent scale factors in the R direction, namely second scale factors, C, D and F can be valued in (0, 1) according to the wheel disc features and feature point positions, C is smaller than D and smaller than F, for example, C can be valued as 0.1, D can be valued as 0.3, F can be valued as 0.9, and the values of C, D and F can be specifically and custom set according to practical conditions, but the embodiment is not limited thereto. K can represent the slope of the tip face, i.e. the slope of the tip face of the blade model near the bottom end of the blade disk model, R6 and R12 can be calculated by calculating the slope of the blade bottom face and extending in the direction of the front and rear edges.
When the coordinate values Z1-Z12 of the target structural feature points 1-12 in the Z direction and the coordinate values R1-R12 of the target structural feature points 1-12 in the R direction are obtained, the specific ZR coordinates on the target structural feature points 1-12 can be obtained quickly, so that the target structural feature points of the leaf disc model are obtained through the calculation of the blade endpoint coordinates, the calculated amount is low, the construction efficiency of the leaf disc model can be effectively improved, and the design construction period of the leaf disc model is shortened. Meanwhile, according to the characteristics of the wheel disc, coordinate values of target structural characteristic points are calculated by adopting different technological parameters of the leaf disc, such as scale factors, and the like, so that the generated target structural characteristic points more accord with structural characteristics of a leaf disc model, and the accuracy of the constructed leaf disc model is effectively improved.
In an example embodiment, the target structural feature points may be two-dimensional structural feature points of the pre-generated leaf disc model on the meridian plane, specifically, the leaf disc model matched with the leaf model generated based on the target structural feature points may be implemented through the steps in fig. 5, and referring to fig. 5, the method specifically may include:
step S510, constructing a leaf disc meridian plane structure diagram based on the target structure characteristic points;
And step S520, generating a leaf disc model matched with the leaf model according to the leaf disc meridian plane structure diagram.
The structure diagram of the meridian plane of the leaf disc is a structure characteristic diagram corresponding to the She Panmo type meridian plane, specifically, after the target structure characteristic points are determined, connection can be performed between the target structure characteristic points according to the wheel disc characteristics, and the structure diagram of the meridian plane of the leaf disc corresponding to the She Panmo type is obtained.
The leaf disc model matched with the leaf model can be generated according to the She Panzi noon structure chart, and specifically, an OCC tool interface can be called, the leaf disc meridian structure chart is input into the OCC tool interface, and the leaf disc model matched with the leaf model is generated. Of course, other types of three-dimensional geometric design tools may be used to generate the leaf disc model according to the leaf disc meridian plane structure map, for example, autoCAD may also be used to generate the leaf disc model according to the leaf disc meridian plane structure map, and the three-dimensional aggregate design tool used in this example embodiment is not limited in particular.
Alternatively, a new target structural feature point may be generated in response to a position adjustment operation on the target structural feature point, and a leaf disc meridian plane structure map may be constructed according to the new target structural feature point.
The position adjustment operation refers to an operation of adjusting the generated target structural feature point by the user, for example, an operation of adjusting the coordinate value of the target structural feature point by the user through a touch or a mouse drag manner, or an operation of directly inputting a new coordinate value to adjust the target structural feature point through a provided coordinate value modification window of the target structural feature point, and the type of the position adjustment operation is not particularly limited in this example embodiment.
After the new target structural feature points are obtained according to the position adjustment operation, a leaf disc meridian plane structure diagram can be directly constructed according to the new target structural feature points, compared with the situation that She Panmo type integrity is required to be adjusted when a leaf disc model is required to be adjusted in the related art, the embodiment can realize integral modification operation of the leaf disc model only by adjusting the target structural feature points of the leaf disc model on the meridian plane, adjustment of the target structural feature points in two dimensions is far simpler than adjustment of the leaf disc model in three dimensions, workload is small, construction or adjustment modification efficiency of the leaf disc model is effectively improved, construction and design difficulty of the leaf disc model is reduced, the leaf disc model can be suitable for various types of leaf models, and dependence on professional designers is reduced.

Referring to fig. 6, after the generated target structural feature points are obtained, a leaf disc meridian plane structure map 610 corresponding to the current target structural feature points may be obtained; in response to the position adjustment operation on the target structural feature points, new target structural feature points can be obtained, a new leaf disc meridian plane structure diagram 620 can be generated according to the new target structural feature points and the size data of the set fillet chamfer angles, and the leaf disc model can be quickly designed or adjusted and modified by adjusting the generated target structural feature points, so that the design period is effectively shortened.
Alternatively, the width of the unit leaf disc can be determined according to the input number of the blades, then the unit leaf disc model can be constructed based on the She Panzi noon structure diagram and the width of the unit leaf disc, and further the integral leaf disc model matched with the blade model can be obtained by rotationally copying and modeling the unit leaf disc model.
Fig. 7 schematically illustrates a schematic diagram of generating a blisk model according to some embodiments of the present disclosure.

On the one hand, target structural feature points can be directly generated according to input blade basic data, and then a leaf disc model can be generated according to the target structural feature points, so that the proportion of manual participation in the construction process of the leaf disc model is effectively reduced, and the construction flow of the leaf disc model is shortened; on the other hand, when the design of the blade model changes, the integral blade disc model does not need to be readjusted, the target structural feature points corresponding to the blade disc model can be directly adjusted, the workload required by She Panmo type adjustment is effectively reduced, and the construction efficiency of the blade disc model is further improved.
