Description
Technical field
The utility model belongs to technical field of civil engineering, is specifically related to a kind of the synchronous with moving device of material and the multidirectional loading of the accurate big stroke of simulation of structural test that be used for.
Background technology
Material and structure testing machine have been widely used in fields such as building, mechanical engineering as a kind of important testing equipment, and are bringing into play important effect in the test of the mechanical properties such as stretching, compression, bending and shearing of metal, plastics, cement, concrete and other materials.Structural test in machinery, field of civil engineering often needs the multidirectional stressed of model configuration.When the multidirectional loading of simulation, since influencing each other between the load, big or small can the change to some extent of power that makes loading position and apply.As when structure is applied the test of vertical force and horizontal force simultaneously, because the effect of horizontal force, the horizontal shift that test specimen produces is all influential (when big stroke loads to the displacement of size, direction and the vertical force generation of vertical force, this problem will be more serious), this makes the test distortion can't truly reflect the influence of P-Δ effect.At present domestic existing testing machine is carrying out multidirectional while during load test, can't realize test specimen loading with moving synchronously in moving process, this has limited the range of application of testing machine, especially load and when moving, existing testing machine can not meet the demands at all in the complexity of simulation large scale structure.
Summary of the invention
The purpose of this utility model is to propose a kind of multidirectional loading synchronous of the big stroke of testing machine that can effectively avoid loading distortion and follows moving device.
The multidirectional loading synchronous of the big stroke of the testing machine that the utility model proposes is with moving device, by loading actuator 1, carriage 2, guide rail 3, displacement transducer 4, with moving device 5, chassis wall 15 is formed (as shown in Figure 1), carriage 2 is connected to form (as shown in Figure 2) by slide block 7 and roller bearing 6, with moving device 5 by roller bearing 12, slide block 10, be connected to form (as shown in Figure 3) with moving actuator 9 by web member 11, guide rail 3 is twice up and down, be fixed on the chassis wall 15, the roller bearing of both sides up and down 6 of slide block device 2 places between the twice guide rail 3, can in guide rail 3, be free to slide, also place twice guide rail 3 middle with the upper and lower sides roller bearing 12 on the moving device 5, can in guide rail 3, be free to slide, slide block 10 links to each other with guide rail by lock-screw, displacement transducer 4 one ends link to each other with chassis wall 15, the other end links to each other with loading actuator 1, load actuator 1 and link to each other by bolt 8, load actuator 1 and link to each other with moving actuator 9 by on connecting rod member 14 and following moving device 5 with the slide block 7 of carriage 2.
The course of work of the present utility model is as follows: when carrying out load test, test specimen is placed the below that loads actuator 1, be connected on the start head that loads actuator, adjust then with moving device 5, slide block 10 is adjusted in the appropriate location along guide rail 3, and locking lock-screw 13.When test specimen being carried out vertical and level when loading simultaneously, because horizontal force action, relative horizontal shift takes place in the loading actuator 1 on test specimen and the upright position, the micro displacement amount is obtained by displacement transducer 4, and feed back in following moving actuator 9, with moving actuator 9 push-and-pull vertical loading actuator 1, eliminate this relative horizontal shift, make vertical loading actuator 1 be positioned at all the time test specimen directly over.Dispose this device equally in vertical direction and also can eliminate vertically opposite displacement.
The utility model adopts line trace monitoring technology to combine with feedback control technology, utilizes Hydraulic Servo Control to realize tracking to loading position.Can avoid loading distortion phenomenon effectively, for the test of implementation structure overall process lays the foundation.The big multidirectional loading synchronous of stroke is that the Displacement Feedback that loading force produced by displacement transducer is in the work actuator with moving apparatus features, correct loading direction and the loading position that loads actuator by servocontrol, thereby eliminate the additional displacement that loads actuator.
In the utility model, used loading actuator, displacement transducer, all be commercially available, very strong versatility and practicality are arranged with all parts such as moving actuator.
At present, the testing machine of material that domestic testing machine producer is developed and structure testing machine, external import does not all possess this function, and testing machine has lagged behind actual needs aspect functional requirement.It is multidirectional synchronously with moving loading problem that the big multidirectional loading synchronous of stroke fundamentally solves big stroke with moving device, makes the testing machine multidirectional loading simultaneously of large scale structures such as phantom frame, shear wall, node, post and member truly.
The utility model is simple and reasonable, and is novel, is easy to implement.
