摘　　要：针对压缩机入口管道振动问题,通过对管道进行模态分析和谐响应分析,研究管道管卡的支撑位置和数量对管道振动的影响,提出管卡数量和位置的设置应以最大程度提高管道固有频率和降低振动位移为原则。随后以某压缩机入口管为研究对象,按上述原则逐个确定了3个管卡的位置,结果表明管道在两横向上的振动位移比原三管卡管道的振动位移分别降低了88.12%和54.8%,减振效果明显。In an attempt to tackle the problem of pipeline vibration,modal analysis and harmonious response analysis on the inlet pipelines of reciprocating compressors have been carried out to study the influence of the position and quantity of pipe-clamps on pipeline vibration.A principle whereby the position and quantity of the pipe-clamps should be set to make the resonant frequency as large as possible and the vibration displacement as small as possible is proposed.With this principle,three pipe-clamps were set one-by-one on the inlet pipeline of a reciprocating compressor.The two horizontal vibration displacements of the thus-supported pipeline decreased respectively by 88.12%and 54.8%compared to the vibration displacements of the pipeline with the original design of three pipe-clamps,representing a significant reduction in pipeline vibration.
