摘　　要：针对某海洋石油钻井平台注水泵机组轴承频繁失效而影响正常生产的问题,以减小注水泵振动为出发点,采用多点布局测振方案对注水泵机组轴承关键点振动特性及平台甲板振动特性进行测试分析,找出导致轴承失效的主要原因。在建立平台甲板CAE模型基础上进行模态分析,提出解决注水泵机组轴承失效问题的平台甲板改造方案。注水泵机组在甲板改造后振动强度明显降低,注水泵机组轴承频繁失效问题得以解决,证实测振技术及基于CAE模型的模态分析技术在分析处理海洋钻井平台注水泵机组故障中的有效性。Regular production was affected because of the frequent failure of injection pump units on marine drilling platforms.In order to solve the problem,vibration reduction of the pumps is studied.First of all,the measurement scheme of multi-spot layout is used to measure the vibration characteristics at the critical points of the bearings of the pump unit and the deck of the platform.And the measurement data is analyzed to find the main reason of the bearing failure.Then,the CAE model for the marine drilling platform is established and the modal analysis is carried out accordingly.Finally,the improvement scheme of the platform deck is proposed to solve the problem of bearing failure of the pump units.It is shown that the vibration intensity of the pump unit is reduced significantly after the improvement of the deck,the problem of frequent failure of the bearings of the pump unit is solved,and the effectiveness of the technology of vibration measurement and modal analysis based on CAE model in analyzing and processing failure of injection pump unit on marine drilling platform is proved.
