Abstract

The working process of a vertical axis automatic washing machine is divided into three Successive steps: washing, rinsing and spin-drying. An automatic washing machine undergoes rotational unbalance due to unbalanced mass during the spinning process. The imbalance may cause serious vibrations in the third step while ramping up to high speed. A liquid balancer assembly and suspension system plays a vital role in controlling this unbalance. In spin cycle, tub hit the cabinet and creates the objectionable noise the main parameters include rotational speed, eccentricities of the center of rotation, hydraulic force (restoration force), and Degree of Freedom. This paper includes Design and Development of a new suspension system with the help of CREO and Analysis tool ADAMS of vertical axis washer. Simulation performed on washing machine during spin-drying mode, and results will be compared with existing data.
