Testing device for dynamic performance of actuator

The invention discloses a testing device for dynamic performance of an actuator. The testing device comprises a computer, a data acquisition module, a dynamic displacement tester, a signal conversion module and a driving module, wherein the driving module and the actuator form a driving loop; the signal conversion module is connected into the driving loop in series; a data input end of the signal conversion module is connected with the dynamic displacement tester; a data output end of the signal conversion module is connected with the computer by the data acquisition module; the computer is connected with the driving module by a data bus and is used for sending a driving parameter to the driving module; the driving module is used for loading a driving signal to the actuator through the signal conversion module according to the received driving parameter; a dynamic performance parameter of a movement piece in the actuator is fed back into the computer to be subjected to parameter calculation, and an instant value of the performance parameter is displayed. The testing device has the advantages that the structure is simple and the precision is high; parameters such as dynamic resultant force of the movement piece in working processes of the different actuators can be tested; furthermore, the consistency of the performance of actuator elements is detected.
