摘要
研究了受到打击的空间多刚体系统考虑库仑摩擦时动力学的求解方法,在引入新的无量纲的时间参数后。通过建立相应的动量-冲量的一阶微分方程,将在趋近于零的冲击区间的讨论变为在有限区间中来分段研究含滑动-粘滞的冲击过程,得到了受到打击的空间离散系统考虑库仑摩擦时的动力学的求解方法。
This paper studied the solution of impulsive dynamics of multi-rigid-body systems with friction. By introducing a new dimensional time parameter,the first-order momentum-impulse differential equations were obtained , and the discussion over infinitesimal impulsive interval was transformed into a piece-wise study on the finite region of impulse,so the solution of impulsive dynamics of spatial discrete system with friction was obtained, i. e. , the dynamic response after the impact can be obtained according to the initial conditions before the impact.
