摘要： 机械设备振动和设备组成、工作机理、工作状态等息息相关，船用常见设备如水泵、风机等由于工作机理各不相同，其振动频率特性也各不相同。通过对旋转类设备振动特征进行对比分析，分析设备主要振源及其成因，提出设备改进方向，并进行针对性改进设计，试验结果表明，取得了良好的效果。

Abstract: The marine equipment includes seawater marine pump, drainage pump, screw pump, hydraulic pressure pump, air-conditioning chilled water pump etc. These pumps work with various forms including rotation, reciprocation, meshing etc., and vibrate with different frequency characteristics. In this paper，the vibration levels, characteristics and causes of different rotational marine pumps were analyzed. Some measures for vibration reduction were proposed and applied to the improvement design of some pumps. The results of testing showed that the vibration level of these pumps was reduced as the expected.

Key words: vibration and wave, blade pump, low noise design
