摘要
以某微型电动汽车实车参数为依据,基于动力学软件ADAMS,结合应用Hypermesh、Nastran模态分析软件,建立该微型电动汽车的刚柔耦合虚拟样机模型,并通过将仿真试验与实车试验数据结果对比分析,检验虚拟样机模型是否正确。以正确的虚拟样机模型为研究基础,分别改变该微型电动汽车前悬架横向稳定杆的长度、宽度、直径及与悬架的安装位置,探究横向稳定杆对整车性能影响。结果证明,增加横向稳定杆的直径即适当加重横向稳定杆,可有效改善汽车的侧倾特性跟纵倾特性。
It is based on the real mini electric vehicle parameters,combined with model analysis software Hypermesh,Nastran,and the rigid-flexible coupling virtual prototype model of the mini electric car has been built based on ADAMS/Car.And the virtual prototype model has been corrected through contrasting the result of simulation test and vehicle test data.Based on the correct virtual prototype,two kinds of methods have been used to establish flexible anti-roll bar,and the length,width,diameter,the installation position of suspension have been changed to explore the anti-roll bar effect on vehicle performance. Through the simulation result,it can get that exaggerating the diameter of the anti-roll bar can improve trim and roll features of the mini car.
