摘　　要：本文介绍了管道振动的基本理论,分析了导致注汽站管道振动的主要原因,提出了相应的减振方法;同时,本文从有限元和振动相关理论出发,给出了管道防振设计的基本思路,并利用有限元软件对某注汽站高压给水管道进行声学模拟、模态分析及热应力计算。通过优化管道布置,实现了该管道的防振设计,得到了良好的结果,验证了本文防振设计思路及动力学分析方法的可行性。This paper introduces the basic theory of pipeline vibration,analyzes the main causes of pipeline vibration in steam injection station,and puts forward the corresponding vibration reduction methods;At the same time,based on the theory of finite element and vibration,this paper gives the basic idea of pipeline anti vibration design,and uses the finite element software to carry out acoustic simulation,modal analysis and thermal stress calculation of the high-pressure water supply pipeline of a steam injection station.By optimizing the pipeline layout,the anti vibration design of the pipeline is realized,and good results are obtained,which verifies the feasibility of the anti vibration design idea and dynamic analysis method in this paper.
