Modeling and Analysis of suspension system of a horizontal axis washing machine

Abstract

In this paper, we present the multi-body dynamic model of a horizontal-axis washing machine and its validation. It will be described alternative approach for modeling and simulation of washing machines as rigid multibody systems (MBS). In that way, one may achieve more efficient and simplified approach for automatic setting of differential equations for motion as well as more suitable for parametric simulation. Moreover, the proposed model will be used to design and test new solutions to improve the dynamical response and to reduce vibrations of washing machine. In order to prove it, we have demonstrated it on washing machine as planar rigid MBS within the Symbolic Toolbox of MATLAB environment.
