以某乘用车悬架为对象，进行悬架系统前悬架、压缩弹簧、前减震器、横向稳定杆、后悬架、空气弹簧、后减震器、扭转横梁设计，并且建立了麦弗逊前悬架三维模型、扭力梁后悬架总成，同时进行了横向稳定杆的有限元分析。

英文摘要：

The design of the suspension system was proposed, with the object of some passenger cars＇ suspension, which including the design of front suspension, the design of compression spring, the design of the shock absorber, design of transverse stability bar, design of rear suspension, design of air spring, shock absorber and design of reverse beam. The three dimensional modeling of the front McPherson independent suspension and rear torsion beam suspension was established, and the finite element analysis of transverse stability bar was presented simultaneously.
