摘要:
基于多体动力学理论,通过 ADAMS/CAR 建立双横臂悬架的仿真模型。采用 DOE 试验设计方法对悬架模型进 行优化,判断对悬架 K&C 特性影响较大的关键硬点。结合 NSGA-Ⅱ遗传算法,利用 ADAMS-ISIGHT 联合仿真对硬点进行多 目标优化,获得关键硬点的 pareto 最优解集。通过验证,结果表明,优化后的双横臂悬架在车轮跳动过程中,车轮前束角、外 倾角和轮距变化范围更小,有利于减少轮胎磨损,提高汽车操纵稳定性。
Abstract:
Based on the multi-body system dynamics theory, the model of the double wishbone independent suspension is built in adams/car software. The model of the double wishbone suspension is optimized by DOE design method. The key hard-point with a big influence on suspension K&C performance is judged. This paper uses the improved genetic algorithm NSGA-II and the joint simulation method of ADAMS and ISIGHT to solve hard point of multi-objective optimization problem, and obtains the Pareto diagram of the hard point. The experiment result shows that the values of toe angle, camber angle and wheel travel track are reduced. The optimized suspension is beneficial to decrease the tire wearing, and improve vehicle handing stability.
