采用ADAMS/View提供的参数化建模及参数化分析方法,对6×6越野汽车前独立悬架进行了参数化设计,并对悬架主要的几何参数进行了分析,得出了较好的分析仿真结果.整个过程首先根据整车设计条件确定悬架的尺寸参数和车轮的定位参数,然后利用AD-AMS/View建立悬架的虚拟样机模型,最后对所建立的模型进行设计研究(design study)和试验设计DOE(Design of Experiments).通过分析得出随下摆臂的长度值增大和下摆臂的安装倾角的减小,车轮侧向滑移量有大幅减小的趋势.因此选择下摆臂的长度值及其安装倾角为设计变量,以车轮侧向滑移量为设计对象,在ADAMS/Insight中进行了参数优选,得出的仿真结果能够满足设计要求.该方法提高了悬架的设计速度与质量,可为今后设计高性能的悬架系统提供借鉴.
Adopting the parametric modeling and parametric analysis method provided by ADAMS / View, the parametric design of 6 × 6 independent suspension before off-road vehicle was carried out. And the main geometric parameters of the suspension were analyzed, and the better The simulation results are analyzed.The whole process first determines the size parameters of the suspension and the positioning parameters of the wheel according to the vehicle design conditions, and then establishes a virtual prototype model of the suspension by using AD-AMS / View, and finally designs the model study and DOE (Design of Experiments) .According to the analysis, it is found that with the increase of the length of the lower arm and the decrease of the mounting angle of the lower arm, the lateral slip of the wheel tends to decrease greatly. Length value and its installation inclination as the design variables, the side slip of the wheel is taken as the design object, the parameters are optimized in ADAMS / Insight, the simulation results can meet the design requirements.This method improves the design of the suspension Speed and quality, can provide reference for the design of high performance suspension system in the future.
