【摘要】 通过建立四杆式双横管独立悬架的运动分析模型，运用经典力学的非自由质点系概念列出约束方程，然后构造一个优化函数，采用工程优化方法求解约束方程.通过计算机的仿真计算来分析汽车悬架在转向和跳动工况下的定位参数和运动参数的变化.文中建立的运动学模型还可以用于普通民根臂式、料管式、纵臂式悬架的运动分析.最后给出了一个实例分析.更多还原

【Abstract】 By setting up a dynamic model of four-link front suspension, an equation of condition with the concept of non-free point particle system of classics is listed, and then an optional function is constructed. This equation is explained with optional method. The alignment and dynamic parameters modifications of the vehicle suspension under the condition of steering and bouncing are analyzed with the numerical simulation on the model described. This model is also applied in the dynamic analysis of wishbone, scmi- trailing arm and trailing arm. An example is shown at the end of the thesis.更多还原
