基于ADAMS的新能源汽车悬架参数仿真与优化设计

Simulation and optimization design of suspension parameters of new energy self-driving vehicle based on ADAMS

在ADAMS软件中建立新能源汽车前悬架运动学仿真模型进行跳动试验,对汽车车轮定位参数进行分析,找出不合理的参数,并对ADAMS软件的优化模块中不合理的参数进行优化设计,从而提高汽车的行驶平顺性。

In recent years,the development of new energy self-driving vehicle technology is getting faster and faster.Since self-driving vehicles have to be highly adaptable to all kinds of road conditions,it puts forward higher requirements for vehicle suspension.Because of the unreasonable design of the suspension wheel alignment parameters of some driverless vehicles,the wheels cannot be righted in time and the wheels can easily run off.In this paper,the virtual prototype technology is used to establish the kinematics model and simulation model of the unmanned vehicle in the modeling software,and the run-out test is carried out.By analyzing the wheel alignment parameters in Adams,the unreasonable parameters are obtained,and optimized in the software optimization module,so as to provide reliable data for future real vehicle research and development and improve the ride comfort of the vehicle.
