| Abstract: | A dynamic model of two-degree-of-freedom vibro-impact system with dry friction excitation is established.The gliding,stick sliding,scratch cutting and collision are analyzed,and the equation of motion and the engagement conditions are worked out.The complex dynamics behavior is solved and analyzed by employing the value iteration method.And the influence of dry friction and the drive oscillation amplitude on the systems dynamics is studied. |
