Description

technical field [0001] The invention relates to an automobile testing device and a testing method, in particular to a multifunctional testing platform for an automobile suspension system and a testing method thereof. Background technique [0002] Suspension is one of the important assemblies of modern automobiles. It is a device that connects the frame and the axle. It can moderate the impact force transmitted to the frame from uneven and undulating roads and attenuate the vibration caused by it. When testing the suspension system, the traditional pure computer simulation uses the method of establishing a mathematical model for simulation. Although the implementation efficiency is high and the cost is low, the simulation results largely depend on the accuracy of the mathematical model and cannot be effectively Reflect the real road environment. The real vehicle road test will be affected by hardware cost and environmental factors, and it is difficult to test the suspension ...
