Research on electromechanical coupling and bending-torsion vibration of the belt driver mechanism

The belt driver mechanism of the electromechanical coupling and bending-torsion coupled nonlinear vibration differential equations are established according to Lagrange-Maxwell equation and the numerical analysis are carried out. States of the nonlinear characteristics of electromechanical coupling system are analyzed by means of Runge-Kutta method. The phase diagram, time response, frequency map and axis trajectory are received. There is obvious unstable phenomena when motor in state of rated operation. The effect of torsional vibration on motor is not obvious.
