A Study on the Dynamic Behavior and Comparative Analysis of a Suspension Type Pulsator/Drum Type Washing Machine

현가형 펄세이터 세탁기와 드럼형 세탁기의 동특성 해석 및 비교 분석

Vibration problems are an intrinsic characteristic in a washing machine owing to rotation working mechanism. Therefore, a right comprehension of working principle and the analysis on dynamic behavior of a washing machine is essential to design anti-vibration or vibration reduction. In this paper, we choose two kinds of a washing machine: a suspension type pulsator/drum type washing machine. Each the structure and working principle of a washing machine is discussed briefly and the dynamic behavior of it is investigated, then, the vibration detection problems of transient or excessive vibration is tented in each category. Some vibration experimented results in a washing machine are presented also.
