Nonlinear Dynamic Analysis of Rigid - Loose Coupling Bidirectional Vibrating-Crushing System

Abstract:

The vibratory crusher with two cavities and four jaws is a new superfine crusher, which is a nonlinear vibrating system with rigid - loose coupling. In order to make clear the dynamics performance of the crusher at work, a model of rigid - loose coupling bidirectional vibrating-crushing system is established, according to the structural characteristics and working principle of the crusher. By using four-order Carl Jung Kutta method,we have gained the time history of displacement, velocity, and acceleration, the displacement spectrum and the hysteretic impact force. From it we can see that the vibration of mass to the left and right side is asymmetric, and the impact of the mass on bulk materials of two sides is asymmetric, although the model is structurally symmetrical.
