When impact applies on a discrete system in which one of constraints is a constant with coulomb friction, the phenomenon of slip - stick at the point can cause the change of friction and the integration for frictional force during infinitesimal impulsive interval becomes impossible according to traditional impulsive dynamics of discrete systems. by introducing a new dimensional time parameter, first - order momentum - impulse differential equations are obtained and the discussion over infinitesimal impulsive interval is transformed into a piece - wise study on the finite region of impulse
在引入新的無量綱的時間參數后，通過建立相應的動量-沖量的一階微分方程，在趨近於零的沖擊區間的討論變為在有限區間中來分段研究含滑動-黏滯的沖擊過程，得到了受到多點打擊的離散系統考慮庫侖摩擦時的動力學的求解方法，即根據沖擊前的初始狀態無需回到繁瑣的微分方程的求解便可以得到沖擊后系統的動力學響應。
