摘要
步行车辆在快速运动中,既有大刚体运动又有小弹性位移,且还有不连续的边界约束条件,是一个很复杂的动力学问题。本文用有限元方法建立了该系统的动力学模型,采用分段的直接积分法求解其弹性动力响应。
A method is presented for dynamic analysis of walking vehicle systemwith large gross motion, small elastic deformation, and discontinuousboundary constraints. The dynamic finite element equations of the systemare developed, and the elastic responses are solved by sectional directintegration method.
