汽水管道振动诊断与评价研究

Study on Vibration Diagnosis and Evaluation for Water & Pressure Piping Sysem

分析了汽水管道系统振动的危害及成因,论述了开展管道系统振动诊断与评价的意义,介绍了开展管道系统振动诊断与评价研究的技术路线,所采用的测试技术与振动模态计算分析方法,以及原因分析方法与振动治理思路。在调研国内外振动评价方法的基础上,结合实际需求,提出了建立管道振动状况评价准则的建议。

The root courses of pipe system vibration are very complicated, and vibration harm is various.Yet the testing and analysis of vibration for pipe system is far less strengthened than that for components.in this article,analyzed the harm and root courses of the vibration diagnosis and evaluation nose and vibration evaluation for piping of water ＆ steam pressure piping system vibration, expounded the value for the piping system.Introduced the technique route of vibration diagsystem vibration,testing and analysis techniques and practice application.Finally,proposed the evaluation criteria for pipe vibration.
