摘要
为分析某汽车底盘平台对不同车型操控稳定性以及平顺性的适应性,以VC++和ADAMS,开发了底盘平台悬架分析专用模块,该模块可以快速建立前后悬架、其它子系统以及整车的参数化模型,并能快速完成操控稳定性和平顺性的分析优化。通过该模块对两款采用该底盘平台车型A1、A2的前、后悬架进行了运动学仿真分析并建立了整车仿真模型,同时根据国家标准应用该模块对两款车型进行了操纵稳定性的转向脉冲仿真分析、计分评价、偏频测定仿真,以及随机路面平顺性的分析。研究结果表明该专用模块具有较好的工程应用价值,采用该底盘平台的两款车型具有较好的操控稳定性和平顺性。
In order to analyze the adaptation of an automobile chassis platform in handling stability and ride comfort when assembled in different car models,VC＋＋ and ADAMS were used to develop a specific simulation module for suspension performance analysis of the chassis platform,which could not only create the parametric modeling of the front and rear suspension,the other subsystems and the whole vehicle quickly,but also accomplish the analysis and optimization of handling stability and ride comfort.By adopting this module,kinematic simulation analysis and vehicle simulation model for the front and rear suspension of this chassis platform when assembled in two different cars models named A1,A2 were carried out,then steering pulse simulation analysis which can reflect handling stability,score evaluation and analysis of ride comfort in random road were proceeded according to the national standards.The results show that this simulation module has superior application value in engineering and the two different car models equipped with this chassis platform have better handling stability and ride comfort.
