ABSTRACT
The paper describes a dynamic model of a shearer’s cutting system using the KSW-500 shearer as an example. The dynamic model is composed of a physical model characterized by a discrete structure and of a mathematical model, which constitutes a set of relations and a system of ordinary differential equations of the second order. Vibrations are forced by resistances to cutting of rock by means of conical cutting tools. The system of differential equations has been solved by the Runge-Kutta iterative method.
