摘　　要：悬架采用双横臂式独立悬架结构,主要设计要点是四连杆硬点布置,只有最优的双横臂布置,才能得到最优的悬架系统,使整车在行驶过程中产生最小的轮胎磨损,提高整车的横向稳定性。文章在ADAMS View建立了独立悬架参数化模型,通过设定设计变量,设定目标函数,对目标值求最优解,最终仿真优化出最优的悬架硬点布置。通过仿真结果表明:优化后的结果较初定的四连杆机构有很大的改善。The suspension adopts a double-wishbone independent suspension structure.The main design point is the layout of the four-link mechanism.Only the optimal double-wishbone layout can obtain the optimal suspension system,which minimizes the entire vehicle during driving.Tire wear improves the lateral stability of the vehicle.In this paper,a parametric model of independent suspension is established in ADAMS View.By setting design variables,setting objective function,and finding the optimal solution to the target value,the simulation optimizes the optimal suspension hard point arrangement.The simulation results show that the optimized results are greatly improved.
