Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, is intended to be illustrative, and not restrictive, and any other similar items may be considered within the scope of the present invention. In the following detailed description, directional terms, such as "left", "right", "upper", "lower", "front", "rear", and the like, are used with reference to the orientation as illustrated in the drawings.
As shown in fig. 1, the method for constructing a digital prototyping cooperation system of a physical product according to a preferred embodiment of the present invention comprises the following steps:
acquiring a digital prototype of the physical product from a model database;
splitting the physical product into a plurality of configuration items based on a preset modular splitting rule;
according to the configuration items obtained by splitting, decomposing a digital prototype of the physical product into a plurality of corresponding digital prototype modules, and storing the digital prototype modules obtained by decomposition into the model database;
carrying out lightweight processing on the digital prototype module to obtain a lightweight digital prototype module;
and constructing a digital prototype cooperation system by associating the model database and the lightweight model database, wherein the lightweight model database stores all lightweight digital prototype modules.
The modular splitting rule can be formulated based on the structural division and the functional division of the product, and the configuration items formed by splitting the product correspond to the digital prototype modules contained in the corresponding digital prototypes one by one.
For example, the modular splitting rule may be formulated based on configuration regulatory requirements of the product. According to some preferred embodiments of the present invention, the method can be used for constructing a digital prototype collaborative system of an aircraft product, and the aircraft product can be decomposed and defined layer by layer based on the idea of modularization of the product structure and the configuration management and control requirements of the aircraft, so as to ensure that the configuration state of the digital prototype is clear. Defining the digital prototype and the corresponding physical product in this way is helpful for facilitating full communication and coordination with users inside and outside the digital prototype model, such as during product development and design.
Referring to fig. 2, a digital prototype of a complex product, such as an aircraft, may also be decomposed according to its product structure, which may be done in the following layers. The first layer is decomposed into sections (such as a machine head, a machine body, a wing and the like), the second layer is decomposed into systems (such as an air conditioning system, a hydraulic system, a fuel system and the like), the third layer is decomposed into system function layers (such as a hydraulic oil tank system function layer, a hydraulic oil filtering system function layer, a hydraulic pipeline system function layer and the like), the fourth layer is decomposed into configuration items for realizing the system functions, the configuration items are connected with corresponding digital prototype modules in a hanging mode, namely the digital prototype modules are associated with the configuration items, the digital prototype modules controlled by the configurations in the product structure are used as the minimum units of the digital prototypes and serve as uniform carriers for professional design and coordination, and through the matching and association relationship between the airplane digital prototype modules and the configuration items, the data integrity is ensured, and the digital prototype configuration states are clear and controllable. Thus, methods according to some embodiments of the present invention may avoid the problem of configuration confusion that is common in the prior art.
According to some preferred embodiments of the present invention, the decomposed digital prototype module has geometric attributes, characteristic attributes and configuration attributes, and the configuration attributes are used for representing the association relationship between the digital prototype module and the configuration items.
Further preferably, the characteristic attribute comprises material attribute, installation requirement and/or data state information, and the configuration attribute comprises configuration item type, applicability and/or use scene information.
According to some preferred embodiments of the present invention, the specific set of geometric, feature, and configuration attributes for a digital prototype module can be customized based on the user's collaborative requirements or desires in the product design. For example, for a digital prototype module, attributes associated with a particular area (e.g., nose, passenger cabin, wings, hangings, etc.), attributes associated with a particular functional system (e.g., fuel, flight control, avionics, power, etc.), data states associated with a particular digital prototype (e.g., version a, version B of the digital prototype, release or design of the digital prototype, etc.), and the like may be defined. For example, the configuration attributes may further include attributes such as rack effectiveness, space range information, and type and applicability of the digital prototype, and the characteristic attributes may further include attributes such as heat load, special risk, load, and fire protection factor.
The definition of geometric, feature, and configuration attributes of a digital prototype module as described above can facilitate the screening and customization of digital prototype modules or lightweight digital prototype modules based on a collaborative platform. As described above, the characteristics or features of the digital prototypes and their modules are defined and labeled according to the service scope, scenario and category of the digital prototypes modules, which is helpful to enable the digital prototypes and their modules to be more conveniently used for collaborative design for different specific service scenarios and specific users.
According to some preferred embodiments of the present invention, the lightening process is to selectively retain the configuration properties and the geometric properties possessed by the digital prototype module, and to remove the remaining properties.
According to some preferred embodiments of the present invention, the geometric attributes retained in the lightening process comprise at least external geometric profile information that can be used to describe the outline characteristics of the configuration item associated with the lightening digital prototype module to which it belongs.
On the basis of the above preferred embodiment of the present invention, for example, the model database (i.e. the original model library) of the customized digital prototype can be lightened according to needs by the specific data interface module, and the process of lightening can filter out other information (such as information of materials, processes, etc. in the digital prototype) in addition to the geometric shape information in the original digital prototype model according to needs. Therefore, the lightweight digital prototype after the lightweight processing and the lightweight digital prototype module contained in the lightweight digital prototype can only have relatively less information including the external geometric outline information. The lightweight digital prototype can be identical in profile size to the original digital prototype, but the filtering of the other information allows the lightweight digital prototype to contain less information than the original digital prototype.
The design is advantageous from two aspects, on one hand, the data volume involved in the design cooperation process performed by the light-weight digital prototype and the light-weight digital prototype module is obviously reduced, which is beneficial to saving resources and improving efficiency, and on the other hand, the light-weight digital prototype and the light-weight digital prototype module can promote the confidentiality of key information in some design processes.
According to some further preferred embodiments of the present invention, the above-mentioned weight reduction process may define the frequency and the conversion time of data weight reduction conversion according to the load-bearing capacity and the peak/trough time period of hardware such as a server (for example, the interval may be defined as daily/hourly/weekly; if the server is busy in the daytime, a time period during which the server is idle at night may be defined to perform the weight reduction process). Meanwhile, the format and the precision of data conversion of the digital prototype can be set, and the related collaborative services can be efficiently developed aiming at different collaborative scenes and objects. For a digital prototype with high cooperative frequency, the local lightweight processing authority of the digital prototype can be transferred to a specific user, and the real-time performance and the effectiveness of the lightweight digital prototype which urgently needs cooperation are ensured. And a prompt or error report can be provided for the conversion failure condition, and an error correction function is configured to ensure that the data after the lightweight processing still has a clear state.
According to some preferred embodiments of the present invention, the step of constructing the digital prototype collaboration system further comprises:
providing a screening tool and a customization tool in the digital prototyping collaboration system, wherein the screening tool is configured to be capable of screening out a target lightweight digital prototyping module meeting requirements from all lightweight digital prototyping modules based on the requirements for one or more of geometric attributes and configuration attributes, and the customization tool is configured to be capable of modifying and mapping the geometric attributes, characteristic attributes and/or configuration attributes of the lightweight digital prototyping modules.
For example, the digital prototype collaboration system can be further developed to provide the following three areas, namely an attribute and state configuration area, a digital prototype module area and a visualization area. And developing the attribute information of the digital prototypes as configurable options in the attribute and state configuration area to ensure that the options based on the attributes can be screened to a corresponding digital prototype list. The digital prototype module area can display a configuration information list of the digital prototypes customized based on the attribute and state configuration in a list. And integrating a digital prototype display tool in a visualization area, ensuring the visualization of the customized digital prototype, and ensuring that a user can carry out operation based on the visualized digital prototype, such as space measurement of the digital prototype, marking of the state of the digital prototype through color control and adjustment, and the like.
According to some preferred embodiments of the invention, the method further comprises the steps of:
setting full access and editing permission for a first class of users to the model database and the lightweight model library, setting partial access and editing permission for a second class of users to the model database and the lightweight model library, setting access and editing permission only for the lightweight model library for a third class of users, and not setting editing permission for a fourth class of users.
The digital prototype cooperation in the traditional mode has the problem of difficult confidentiality: in the cooperation of the digital prototype data with internal and external suppliers and partners, it is difficult to customize the corresponding digital prototype according to the requirement of distinguishing the other party, which may result in providing excessive information and leakage of secret. According to the method of some preferred embodiments of the invention, through the authority setting and control, users at all levels can be ensured to access the model database and the lightweight model database for collaborative design work, the requirement of partners does not need to be distinguished, and the method is helpful for improving the confidentiality of key information in the design process of a digital prototype of a complex product.
Furthermore, for example, for some specific users with access and editing rights, the internal user can also label and customize and package the generated digital prototype model to form a collaborative digital prototype facing the specific user, configuration state information in the collaborative digital prototype is retained, data transmission is performed through other ways such as the existing PDM platform (Product Data Management platform), and the correctness and validity of the transmitted digital prototype can be further ensured manually by the flow and the signature and review personnel.
More specifically, according to some embodiments of the present invention, digital prototype data is stored, the data is classified and stored in a specific address according to development stage, function type, and the like, and corresponding data access rights of different access objects are ensured by setting rights to the address. Different types of users are enabled to access different levels of data.
According to other embodiments of the present invention, as shown in fig. 3, the access and editing rights of the user can be set to 4 levels. The highest layer, such as the access authority of an internal core client, can acquire detailed characteristic information of all digital prototypes and lightweight digital prototypes through the digital prototype construction module; layer 2, the access right of the internal non-core client can acquire detailed characteristic information of a relevant digital prototype or a light-weight digital prototype of a partial region/partial system/partial constraint scene through a digital prototype building module; layer 3, the external core customer can obtain all or specified lightweight digital prototypes (i.e., non-raw data) after data transformation and filtering through the digital prototype building module; layer 4, external non-core customers cannot be authorized by the mock-up module, but can only accept relevant security-reviewed lightweight digital mock-up information via PDM documents.
According to some preferred embodiments of the invention, the method further comprises:
in response to a user's editing of the digital prototype modules in the model database, synchronously updating the editing results of the digital prototype modules with the corresponding lightweight digital prototype modules stored in the lightweight model library, wherein the editing of the digital prototype modules includes modification of geometric, feature, or configuration attributes of the digital prototype modules.
By the method, the editing result saved by the user for editing the digital prototype module in the model database can be synchronously updated to the lightweight digital prototype module stored in the corresponding lightweight model base, so that the validity of the information which can be acquired and edited by the user corresponding to the lightweight model base is ensured.
Further preferably, the method further comprises:
in response to a user's editing of the lightweight digital prototype modules in the lightweight model library, marking the edited lightweight digital prototype modules and/or the digital prototype modules corresponding to the edited lightweight digital prototype modules in the model database to indicate that there is an inconsistency between the edited lightweight digital prototype modules and the digital prototype modules corresponding thereto, wherein the editing of the lightweight digital prototype modules comprises a modification of a geometric, feature, or configuration attribute of the digital prototype modules.
