| 摘 要： | 为研究FSAE赛车侧风稳定性,依据多刚体动力学理论,利用ADAMS软件建立了某FSAE赛车模型及比赛赛道模型.通过与2010年中国方程式汽车大赛(FSAE)中车载信息系统所采集数据的对比,验证了虚拟样机模型的准确性.在此基础上,对典型侧风进行了模拟,利用虚拟试验分析了赛车的侧风稳定性.通过对侧风作用下的三自由度赛车模型的分析,利用ADAMS/Insight模块得到了悬架主要结构参数对侧风稳定性影响的灵敏度,并进行优化.优化结果表明,赛车的侧风稳定性得到了提高.

| Abstract: | In order to improve the crosswind stability of formula-SAE racing car, based on multi-body dynamics theory, models of a certain FSAE racing car and race track were established with the aid of software ADAMS. By comparing the model's structure and parameters with the data collected by vehicle data logger in 2010 China FSAE competition, the correctness of the virtual prototyping model was verified. Then, the typical crosswind was simulated and the crosswind stability of racing car was analyzed through virtual test. The sensitivity of suspension main structure parameters oriented to crosswind stability was obtained and optimized by ADAMS/Insight module. The optimization results show that the crosswind stability of the racing car could be improved to some extent. |
