摘　　要：为了研究扭力梁悬架结构对于整车操纵稳定性的影响,通过HyperMesh软件建立不同的横梁开口方向、位置、厚度及衬套安装角度的扭力梁柔性体模型,并建立Matlab与Adams联合仿真程序进行操纵稳定性仿真分析。结果表明:横梁开口方向及横梁位置对于车辆的稳态、瞬态特性影响较大,横梁位置的选择需要综合考虑不足转向与增幅比的影响,横梁开口方向向下有利于提高车辆的操纵稳定性。In order to research the influence of the torsion beam suspension structure on the vehicle handling stability,HyperMesh was used to establish the torsion beam flexible models with different beam opening directions,positions,thicknesses,and bushing installation angles.According to Matlab and Adams,a simulation program for analysis of handling stability was established.The results show that the direction of the beam opening and the position of the beam have a significant impact on the stability and transient characteristics of the vehicle.Beam position need comprehensive consideration of understeer and amplification ratio.The downward opening direction of the beam can improve the handling stability of the vehicle.

关 键 词：横梁开口方向 衬套安装角度 操纵稳定性
