This paper presents dynamic analyses of a front load Samsung Washing Machine conducted as a simplified dynamic model of two degrees of freedom. An automatic balancer method is implemented which utilizes freely moving balancing bodies rotating with the drum to reduce the system vibration. The vibration of the drum caused by the imbalance mass attached to the rotating unit is examined. The equations of motion of the washing machine drum and balancing bodies are derived. Dynamic analyses of the models with different factors that can decrease the efficiency are performed. Each of these factors is studied and their influence on the magnitude of balancing body position errors is determined. Consequently, the efficiency of this self-balancing method is presented and finally, the general conclusion is put forward.
