AI Technical Summary
Existing loading devices are difficult to simulate the pulse-like lateral impacts that vehicles experience during actual driving in low-temperature environments, and the loading methods are mostly static or low-frequency dynamic, which cannot realistically simulate the lateral loads of vehicles.
A device was designed that includes a low-temperature environment simulation chamber, a pulse loading mechanism, a vibration damper fixing device, a control system, and a data acquisition system. The device uses PLC and PID algorithm for closed-loop control, combined with a cold-resistant cylinder and a force sensor, to accurately generate pulsed lateral force. The data acquisition system records the vibration damper response parameters in real time.
Accurate simulation of dynamic pulse lateral force in low-temperature environments improves the accuracy of test results and the coverage of operating conditions, simplifies the test process, enhances the versatility and efficiency of the device, and ensures the stability and repeatability of the applied force.
