摘要
为改善轻型卡车的操纵稳定性,运用ADAMS/Car模块对某轻型卡车的双横臂独立悬架进行建模,通过平行轮跳实验,在ADAMS/PostProcessor中分析车轮定位参数的变化。针对车轮外倾角、前轮前束角、主销后倾角随轮跳变化幅度较大问题,对悬架部分硬点坐标进行多目标优化,通过迭代计算得到最优解。优化后车轮外倾角、前轮前束角、主销后倾角的变化范围符合设计要求,悬架的操纵稳定性提高。
In order to improve the operational stability of light trucks, the model of double wishbone independent suspension of light truck is built based on ADAMS/Car module, and then the analysis of the variation in the wheel alignment parameters is carried out through the parallel （wheel hop experiment in ADAMS/PostProcessor. Intended to solve the problems of camber, toe angle of the front wheel and caster angle range ability with wheel jump amplitude, an optimization of suspension hard point coordinates multi-objective is proceeded to get the optimal solution by iterative calculation. Optimized camber and front toe angle, caster angle variation range accord with the design demands, suspension operational stability is promoted.
