Parametric design and analysis of front independent suspension of 6×6 off-road vehicle with ADAMS/View
-
摘要: 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ADAMS/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.Abstract: Methods of parametric modeling and analysis supplied by ADAMS/View were used to design and analyze front independent suspension of 6×6 off-road vehicle, and better results were received. The whole process is that firstly dimension parameters of suspension were designed according to design conditions, and then virtual prototype model was built in ADAMS/View, design study and design of experiments.DOE(Desidgn of Expeximents) on suspension model were done at last. It can be obtained by analysis that sideways displacement of wheel has a dereasing tendency when length of lower sway arm is growing and assembly angle of lower sway arm is decreasing. So the length and assembly angle of lower sway arm were chosen to be design variables, and sideway displacement is taken as design objective, parametric optimization was done in ADAMS/Insight. The final test results meet demands of design. This method can improve advances design speed and quality of suspension, and can supply reference for designing high performance suspension in the future.
