摘要
针对大学生方程式(FSAE)赛车前轮定位参数的优化设计问题,基于ADAMS/Car模块建立FSAE赛车双横臂独立悬架的仿真模型,对前轮定位参数进行仿真分析。利用ADAMS/Insight模块进行优化设计,确定设计参变量和设计目标,对所选定的设计目标进行影响因素分析;根据优化结果修改前悬架仿真模型,再次进行前轮定位参数的仿真分析。结果表明:赛车车轮上下跳动时,优化后的前轮定位参数能够在合理的范围内变化,满足赛车悬架设计要求,赛车悬架的主要性能得到明显提高。
Aiming to optimize the front wheel alignment parameters of Formula SAE （FSAE） racing car, the simu- lation model of double wishbone independent suspension of FSAE racing car was established based on ADAMS/Car module, and the front wheel alignment parameters were simulated and analyzed. Then the variables of the design parameters and design objectives were determined by using ADAMS/Insight module, and the influence factors on the selected design goal were also analyzed. Afterwards the front suspension simulation model was modified accord- ing to the optimization results, and the front wheel alignment parameters were simulated and analyzed again. The result shows that when racing wheels bounce up and down, the front wheel alignment parameters vary within a rea- sonable range, in which meets the suspension design requirements of racing car, and the suspension performance of racing car is significantly improved.
