MODELLING AND VIBRATIONAL ANALYSIS OF FRONT LOADED WASHING MACHINE

Abstract

Recent environmental awareness requires the improvement of washing efficiency. Talking about efficiency, the first we needs to concentrate on optimization. Basically we need to concentrate on the parameters like supply voltages, mechanical parameters and etc. Many of the above parameters can be approximately optimised by solving the problem of Vibration. In a washing machine, vibration of the outer tub is responsible for vibration of the frame and the force then transfers from the supports to the floor. Although springs and dampers also helps in reducing the vibration, it is very much important to efficiently design the coefficients of stiffness and the damping coefficients of these mechanical components. Thus, number of washing machine vibration analysis models at various speeds have been proposed at various unbalanced condition in this paper. In this paper we are concentrating on reducing the vibrations of the drum with the help of maintaining exact coefficient of dampers and stiffness of the springs.
