Vehicle vibration reduction simulation test method and system

Abstract

The embodiment of the invention provides a vehicle vibration reduction simulation test method and system, and the method comprises the steps of building a vehicle model through host equipment, configuring related parameters of the operation of the vehicle model, and flashing the vehicle model and the related parameters in target equipment; operating the vehicle model based on the related parameters through the target device to simulate the motion of the vehicle model in the road surface, and outputting a road surface excitation signal to a motion controller in the shock absorber actuation system; controlling an actuating mechanism to drive a shock absorber to move vertically through a motion controller based on the road surface excitation signal; obtaining the state parameters of the shockabsorber in the vertical movement process through the target device, and performing the shock absorption simulation test of the vehicle based on the vehicle model, the related parameters and the state parameters. The combined simulation test of the vehicle model and the shock absorber physical movement can be achieved, and therefore the performance of the vehicle can be accurately evaluated.

Description

technical field [0001] Embodiments of the present invention relate to vehicle technology, and in particular to a vehicle vibration reduction simulation test method and system. Background technique [0002] At present, when the performance of the vehicle needs to be evaluated, the vehicle needs to be tested to obtain the evaluation result. Among them, in the vehicle test method, methods such as pure software simulation and real vehicle test are usually used. [0003] Among them, the shock absorber is a key component of the vehicle. The pure software simulation method cannot truly reflect the characteristics of the vehicle shock absorber, so the evaluation of the vehicle may be inaccurate; the actual vehicle test method is in the later stage of vehicle development. The test results are relatively passive to the improvement of vehicle performance.
