摘　　要：随着FSC赛车技术水平不断地提高,悬架系统的设计与优化成为各赛车队争相研究的新热点。以赛车动力学理论为基础进行悬架几何设计,采用Solid Works软件建立某赛车的前悬架三维模型;在ADAMS/Car环境下建立了赛车前悬架转向运动学仿真试验台,结合平行轮跳试验对前悬架运动学特性进行仿真研究;最后以悬架硬点坐标为优化变量,以减小四轮定位参数变化范围为优化目标,运用ADAMS/Insight模块建立了多变量多目标的悬架几何优化模型。仿真结果表明:给出的悬架几何设计方法有效地缩短了赛车研发周期,优化后的悬架几何使得四轮定位参数在轮跳中的变化范围明显减小,有利于赛车操纵稳定性能的提升。With the FSC racing car technology constantly improving, the design and optimization of suspension system has become a new research hotspot. The front suspension geometry design was made based on the racing car dynamics theory, SolidWorks software was used to establish the three-dimensional model of the front suspension and steering system for a eertain racing ear, a front suspension and steering kinemalics simulation test bench was established in ADAMS/Car simulation environment. The front suspension kinematics simulation study was carried out eombined with parallel wheel travel testing. Finally, taking the suspension hard points coordinate as optimization variable, reducing the variation range of wheel alignment parameters as the optimization target, ADAMS/Insight module was used to establistl a muhi-variahle suspension geometry muhi-objective optimization model. The simulation results show that： the suspension geometry design optimization method can effectively shorten the development cycle of the racing car. The optimized suspension geometry makes the variation range of wheel alignment parameters significantly reduce under parallel wheel travel test, the handling and stability for racing car are improved.
