The objective of this paper is to investigate the transmissibility and isolation efficiency encountered with the suspension of a horizontal washing machine. This analysis aims at reducing vibration and noise excited by the rotating unbalance during the spinning cycle of the washing machine. Through parametric analysis of the drum vibration of the washing machine, the detailed effect of the drum mass, suspension stiffness and suspension damping coefficient, it is possible to examine the variation of the transmissibility and isolation efficiency with the spinning speed of the machine. The isolation efficiency is presented for spinning speed from 600 to 1200 rev/min. It is possible through proper selection of the washing machine parameters to increase the isolation efficiency to about 96 %.
