Optimization of a BSC Racing Car's Front Suspension Based on ADAMS

为了提高BSC赛车的操纵稳定性,对其所采用的双横臂式前悬架进行了优化处理。提取CATIA中三维模型的硬点坐标参数,利用ADAMS/Car软件建立了BSC赛车的简化动力学模型,完成了仿真实验台的搭建;应用后处理模块Postprocessor分析了各车轮定位参数的角度变化;利用优化模块Insight对优化目标进行了灵敏度分析,从而完成了双横臂式前悬架的优化。将优化结果用于BSC赛车的悬架设计中,改善了实车的操纵稳定性。通过对虚拟样机进行仿真优化试验,可以快速发现各个优化目标的主要影响因素,明显缩短了悬架系统的设计周期,对同类型的悬架设计起到了借鉴作用。

In order to improve the steering stability of the BSC racing car, the design of the double wishbone front suspension is optimized. By extracting CATIA three-dimensional model＇s hard point coordinate parameters, using software ADAMS/Car to establish the simplified dynamic model and complete the construction of the simulation test bench, the angle change of each wheel alignment parameters is observed and analyzed through post-processing module Postprocessor, using the optimization module Insight to analyze the sensitivity of optimization goal. Finally, the optimization process of front suspension is completed.The results are applied in the design of BSC racing car＇s front suspension, handling and stability is improved for the real car.Through simulation and optimization test of virtual prototype, main factors of optimization goals can be found quickly, design cycle of suspension system can be shorten, providing the reference for the same type of suspension design.
