Abstract: To solve the problem of large load and easy secondary impact on the vertical impact test bench, a dual hydraulic cylinder position synchronization control system and a fast rebound braking system was designed to meet the key technical requirements of the hydraulic control system of the test bench. Firstly, based on the key technical indicators of the test bench, taking into account factors such as actual working conditions and economy, a schematic diagram of the hydraulic control system was designed. Then, for the synchronous control system, a fuzzy controller and synchronization control algorithm model was designed using Simulink software. At the same time, a hydraulic system simulation model was built using AMESim software, and the two models were jointly simulated. The rebound braking systems were modeled and simulated using AMESim software. Finally, the simulation results of fuzzy PID control and conventional PID control were compared. A large vertical impact test-bed was designed and manufactured, and the actual test was carried out, which verified the correctness of the simulation results. The research results show that the maximum synchronization error of the fuzzy PID control method under actual working conditions is 0.09 mm, meeting the synchronization accuracy requirement of 0.2 mm. The use of the fuzzy PID control method has higher synchronization control accuracy and stronger robustness than the conventional PID control method. The working mode of using proportional servo valve and plug-in valve to drive the brake for quick braking of the workbench, with an overall response time of 63 ms, meets the requirement of 100 ms of braking effective time. The maximum synchronization error of the actual synchronous control system is 0.11 mm, which meets the performance indicators and verifies the correctness of the control scheme and simulation.
Key words: large scale vertical impact test; position synchronization control accuracy; rapid rebound braking; fuzzy PID control; joint simulation; proportional servo valve; Simulink; AMESim
