基于 ADAMS／View 微型旅游观光电动汽车悬架仿真分析

摘要

针对唐山电动汽车重点实验室前期研制的微型旅游观光电动汽车在行驶时出现轮胎过大的磨损、自动回正作用较弱、转向沉重等问题，在机械系统动力学仿真软件ADAMS/View中建立此电动汽车的前悬架虚拟样机模型。对此模型进行平行轮跳动实验，来仿真分析其悬架系统参数的变化范围，进而分析其产生汽车不稳定特性的原因，为进一步对悬架系统优化和整车平顺性分析做铺垫。%Aiming at the situation that the micro tourism electric vehicle of Tangshan electric vehicle key laboratory produces excessive wear of the tire in driving、poor self-aligning、heavy steering , creating the electric car front sus-pension virtual prototype model in the mechanical system dynamic simulation software ADAMS /View. Experimen-ting the model by the parallel wheel travel to simulate the range of the suspension system parameter , and then ana-lyze its car unstable characteristics for the further optimization of the suspension and vehicle ride comfort .
