【摘要】 为了满足车辆悬架设计中平顺性与操纵稳定性相互兼顾的需要,基于车辆多体动力学及优化设计原理,在虚拟样机下建立了重型汽车独立悬架的三位数字化模型,并进行了优化设计分析,提出了一种悬架系统参数及系统刚度匹配的悬架优化设计方法。结果表明:采用该方法进行悬架的优化设计,可有效地提高车辆悬架的动态特性;较好地控制悬架刚度随车轮上跳的变化趋势。更多还原

【Abstract】 In order to satisfy the balance between manipulation stability and driving smoothness in the design of vehicle suspension,based on vehicle design optimization and multi-body dynamics,a 3-digital model of heavy truck suspension is developed by virtual simulation,its optimal analysis is carried out,an optimal design method that can make the suspension system parameters match the stiffness parameters is put forward.The results show that: the vehicle dynamic performance can be improved effectively;the direction of suspension stiffness and wheel displacement can be controlled preferably.1 tab,8 figs,10 refs.更多还原
