摘　　要：本文以海上平台用离心压缩机为研究对象,研究并采用大型机组隔振装置(AVM,Anti-vibrationMounting)来减少振动传递。本文计算得到了AVM的动力参数,以保证机组具有理想的隔振率,同时根据计算结果对AVM进行了选型,在机组中得到成功应用。通过数值仿真对该机组的转子和整机动力学特性进行了分析,结果表明,该机组的转子动力特性满足API617要求;在振动传递方面,由于AVM的作用,相邻两台机组基本互不影响,并且,机组的主振型模态与运行区间没有频率干涉,机组的振动满足ISO10816的要求。This paper focuses on the centrifugal compressor used in offshore platform,researches and adopts the AVM(Anti-vibration Mounting)to reduce vibration transmission.The dynamic parameters of AVMs are calculated to ensure an ideal isolation transmissibility.Based on the calculation results,the AVMs are selected and successfully applied in the unit.The rotor and overall dynamic characteristics of the unit are analyzed through numerical simulation.The results show that the rotor dynamic characteristics of the unit meet the requirements of API 617.Due to AVM,the adjacent units have minimal impact on each other,and the primary modal frequencies of the unit do not interfere with the operating speed range.The vibration of unit satisfies the requirements of ISO 10816.
