摘　　要：流体压力脉动和管壁结构作用产生剧烈的管道振动,严重影响设备安全运行。针对该问题,通过对管道振动数学模型及引起振动的流固耦合理论进行研究,重点从管道结构和流体系统两方面对管道产生振动的原因进行了分析,提出了在结构系统、液压冲击、气流脉动等方面消减振动的有效措施。介绍了治理压缩机管道振动的工程实例,结果表明其措施有效。最后,总结了为了控制管道振动,今后应重点发展的方向和重视的问题。The strong vibrations are caused by fluid pressure and the pipeline structure in pipeline systems and seriously affect the operational safety of equipment.Based on this problem,by using pipeline system vibration model and researching the fluid-structure couple theory of pipeline vibration,the paper makes a detailed analysis of the cause from the pipeline structure and fluid system.Then control measures are brought forward from the structural systems,hydraulic impact and gas pulsation.It introduces a governance engineering on compressor pipeline vibration,with the results to show that the measures are effective.In the end,the development priority and problems that need to be emphasized in future for control measures are summarized.
