运用多刚体系统动力学中R-W方法，建立了轮式车辆麦弗逊悬架和转向系统运动方程，导出了系统关联矩阵、通路矩阵、体铰矢量矩阵以及系统约束方程。在此基础上建立了麦弗逊悬架转向梯形断开点位置优化模型。在优化模型中，根据转向要求创建出了一种权重函数,从而可以获得最佳的优化效果。
Abstract
The motion equation of Mc Pherson strut and steering mechanism for wheeled vehicles was established by using the R-W (Roberson R E and Wittenburg J) method known in dynamics of multi- body systems. Systematic incidence matrix, route matrix, body hinge vector matrix and system re-straint equation were derived. On this foundation, the optimization model of the splitting point of Mc Pherson strut and steering mechanism was established. In the optimization model, according to steer-ing request, a weight function was founded to obtain the best optimization effect.
