摘要：         往复式压缩机是工业领域里重要装置之一,振动的问题一直存在于往复式压缩机管系中,通过模态和谐响应分析后得到的结果可以进一步弄清楚结构的振动特性。对某油气田平台上往复式天然气压缩机管系振动问题,通过模态分析和谐响应分析的方法发现了管系的固有频率值与激发频率共振区相重合的问题,由此提出改变支撑位置、合理的添加支撑的方法,通过模拟以及现场实验数据得出管系固有频率值确有提高,有效减小振动的幅值,验证了该方法的可行性。

Abstract: Reciprocating compressor is one of the important equipments in the industrial field. The vibration problem has always existed in the pipe system of reciprocating compressor. By modal and harmonic response analysis, we can get the result that can accurately figure out the vibration characteristics of the structure. Aiming at vibration problems of reciprocating compressor piping of natural gas on the platformi n an oil field, it was found that the natural frequency of the piping was coincident with the resonance region of the excitation frequency by means of modal analysis and harmonic analysis. The method was proposed to change the supporting position and add reasonable support. Through numerical simulation and experiment data, it was found that pipe inherent frequency value was increased effectively, the amplitude of vibration was reduced, and the feasibility of the method was so verified.

Key words: Pipe system vibration,    , Natural frequency,    , Mode,    , Harmonic response
