摘　　要：为解决轮毂电机驱动赛车在高速转弯时产生的侧倾刚度响应滞后及刚度突变问题,使传统赛车悬架系统能够适应新的轮毂驱动形式,我们采用了双横臂式侧纵倾解耦独立悬架设计结构,并取消了原有的部分机械部件,从而有效解决了刚度突变问题。首先,通过选定整车设计和悬架的重要参数;接着开展悬架动力学特性分析,计算悬架刚度等重要参数;然后,利用ADAMS/Car软件搭建悬架多体动力学模型,进行俯仰工况仿真,以评估初始设计结构的合理性;最后,通过ADAMS/Insight工具优化前悬架参数,特别是转向横拉杆两端硬点的位置,保证车轮前束角在合适的范围内,以提高车辆操控稳定性和安全性。In order to solve the stiffness mutation of the roll stiffness response lag in the high-speed turning of the in-wheel motordriven racing car,so that the traditional racing suspension system can adapt to the new in-wheel drive form,by canceling the original mechanical parts and using the double-wishbone side trim decoupling independent suspension design structure,the stiffness mutation problem is effectively solved.Firstly,by selecting the important parameters of vehicle design and suspension;then,the dynamic characteristics of the suspension are analyzed,and the important parameters such as suspension stiffness are calculated.Then,the suspension multi-body dynamics model is built by ADAMS/Car,and the pitch condition simulation is carried out to evaluate the rationality of the initial design structure.Finally,the front suspension parameters are optimized by ADAMS/Insight,especially the position of the hard points at both ends of the steering tie rod,so as to ensure that the toe angle of the wheel is within the appropriate range,so as to improve the vehicle handling stability and safety.
