汽车悬架动力特性试验系统的研制

Study On The Dynamic Performance Test System Of Automotive Suspension

本文应用计算机自动控制变频器技术对机械式悬架试验台进行了功能扩展,使扩展后的试验系统基本上满足了汽车悬架动力特性试验的要求;并运用系统辩识理论对悬架系统进行建模,以对其进行随机激励和各种路面输入的仿真,从而系统评价悬架系统的动力特性。是一套较为完善的悬架动力特性试验系统。

This paper focuses on the function augment ofthe mechanism suspension performance test rig systemby using computer to control transducer atomatically,The expanded system can meet the requirements ofautomotive suspensions dynamic performance test. Andthe system identification theory is applied into thesuspensions modeling in order to simulate thesuspension in random stimulus and in various inputs, sothe suspensions dynamic performance can be estimatedsystematically. It proves to be a more perfect dynamicperformance test system of suspension.
