摘要: 以对某方程式赛车的操纵特性进行动力学虚拟实验分析为目的,应用机械系统动力学仿真软件ADAMS建立了某方程式赛车的虚拟样机模型,并且考虑了空气动力因素。通过与转向盘角阶跃试验采集的数据的对比,验证了虚拟样机模型的准确性。在此基础上,进行了转向盘角阶跃输入、稳态回转、转向轻便性及回正性的虚拟试验。仿真结果表明:赛车瞬态响应较快,并在不同速度下都能保证适度不足转向特性,且转向轻便性及回正性良好。

Abstract: In order to analyze the handling characteristics of a certain formula racing car by virtual dynamics test,by applying the mechanical system simulation software ADAMS,the model of a formula racing car was established with aerodynamic characteristics taken into consideration.By comparing with the experiment date of steering wheel angle step input,the correctness of the virtual prototyping model was verified.Based on these,the handling stability virtual tests such as steering wheel angle step input,steady static circular and steering efforts were performed.The simulation results show that the racing car has rapid transient response and moderate tendency to understeer at various speed,good steer handiness and returnability which provides strong basis for the performance prediction.
