The structure of a top loaded washing machine is analyzed, and the vibration model of the tub is developed. A three-ball model is suggested to simulate balancing the effectiveness and mechanism caused by the liquid in the equilibrium ring. The numerical results of the complicated vibration equations of the tub are obtained by using Runge-Kutta method. Accordingly, an analysis and simulation system is developed to simulate the starting process of the machine. The dynamic characteristics of an actual washing machine are simulated, which explain reasonably the equilibrium mechanism of the equilibrium ring. The numerical results and the simulation system possess important value in the developing and dynamic optimal design of a washing machine.
