为了节约用水而在滚筒洗衣机中使用水泵，可能会使洗涤过程比不使用水泵的洗涤过程更嘈杂，因为水泵通常安装在柜体结构上，作为额外的振动和噪声源。为了通过箱体结构的刚度设计来抵消这种振动和噪声问题，或者从验收试验的角度对水泵进行分类，水泵作为激励源的特性是必不可少的。本文研究了水泵作为激励源的几种表征方法。介绍了用传统方法测量35w水泵的阻塞力和/或自由速度的方法。综述了近年来提出的两种振动功率计算方法。然后，提出了另一种计算振动功率的方法。给出了水泵在梁式结构上运行时的振动功率估计，并进行了比较讨论。
Water pumps used in drum-type washing machines to save water are likely to make the washing process noisier than the one without those because the water pumps attached usually onto cabinet structure work as additional vibration and noise sources. In order to either counteract such vibration and noise problems by stiffness design of the cabinet structure or classify the water pumps from the view point of an acceptance test, characterization of the water pumps as excitation sources would be essential. In this paper, several methods to characterize a water pump as an excitation source are investigated. Measurements by traditional methods of blocked force and/or free velocity for a water pump of 35 W are presented. Two methods of vibration power suggested rather recently are reviewed. Then, another method of the vibration power is proposed. Estimations of the vibration power for the water pump operating on a beam structure are obtained and discussed comparatively.
