摘要: 以某轿车为研究对象,用Adams/car软件建立整车虚拟样机模型,结合虚拟样机模型,将Taguchi稳健优化设计方法应用到平顺性优化设计中,以提高车辆的平顺性。该方法只需少量的试验及简单的信噪比分析,即可得到稳健的设计结果。该结果可以有效地控制不可控因素对车辆平顺性的影响,与传统的优化设计相比更符合实际情况,具有更强的抗干扰能力。

Abstract: Taking a car as research object,the Adams/car Software was adopted to build vehicle virtual prototype model.Combined with the virtual prototype model,Taguchi robust optimum design method was applied to the design of smoothness optimization to improve vehicle ride comfort.With the methodology,only a small number of tests and simple analysis are needed to get reliable results,which can effectively minimize the influence of uncontrollable factors on vhicle ride comfort.Compared with traditional optimum design method,Taguchi robust optimum design method has advantages in producing more realistic results and stronger anti-interference ability.
