摘要
平台上的机械设备在运转时会对平台产生冲击和振动，降低了平台的可靠性。为了降低平台的动载，提高平台使用寿命，阐述了旋转设备振动的产生，从理论上分析了振动产生的原因，提出了在平台上如何设计、安装减振装置来减少振动的产生，为机械设备在平台上更加合理地安装提供了理论基础和参考。
The base of producting crude oil on the sea is offshore platform building,which is assurance to safe operation.With mechanical equipment running ,it impacts platform continuously so that the reliability of platform reduces. For reducing platform＇s dynamic load and prolonging the life of platform,it is necessary to know the causes of vibration obout revolving equipment. And then the causes of vibration are analyzed theoritically. Finally,measures about reducing vibration are put forword.
