随着人们生活水平的提高，小家电诸如榨汁机的普及，使人们越来越重视实用功能外的噪音问题。 小家电的噪音来源有很多，本文研究的KA-J5001L型榨汁机噪音来源主要有电机本身的噪音、过滤网刀盘组件旋转产生 的噪音以及整机振动产生的噪音等。连接头本身的结构问题导致动平衡数据不稳定，直接影响到噪音问题。本文从改变连接 头的结构研究入手，研究哪种结构能够使连接头的动平衡数据更加稳定或趋于小值。

With the improvement of people's living standard, the popularization of small appliances such as juicer, makes people pay more attention to the noise problem beside the practical function. There are many sources of noise in small appliances. The noise sources of KA - J5001L juicer studied in this paper are from the motor itself, the rotation of filter cutter assembly and the machine vibration, etc. The structure of the connector leads to the instability of dynamic balance data and directly affects the noise problems. This paper studies on the structure types of the connector to make the dynamic balance data more stable or smaller.
