摘要
利用悬架的K&C特性试验数据和车辆整车信息及定位参数建立了基于Car Sim的整车模型,并加以验证,分析整车转向特性仿真试验分析麦弗逊悬架K特性对其灵敏度影响,并将灵敏度大的设计因子作为更改前悬硬点的设计目标,联合Adams/Insight软件对前悬硬点做灵敏度分析,找出对该设计因子影响较大的硬点,建立了该悬架硬点与整车转向特性的关联性。
A full vehicle model is established basing on Car Sim using suspension test data of KC characteristics, vehicle information and Wheel alignment parameters, and then verified. Firstly, analyzing the influence of Mc Pherson suspension K to the characteristics of the turning of the vehicle; secondly, finding out the great influence of it as design objective, through the Adams/Insight to do the sensitivity analyze of hard points; lastly, establish the relevance of the suspension hard points and the vehicle steering characteristics.
