摘要
本文以站场旋转机械设备出口管道为研究对象,对其常见振动原因、减振措施进行了总结和分析,探究了站场常见“U”型管道模态规律,得出了其固有频率与管径、曲率半径呈正相关,与壁厚、介质占比、管长呈负相关等主要结论,并在最后给出了此类管道减振的一般步骤,可为同类型管道减振方案的探究提供思路。
In this paper, the outlet pipe of rotating machinery equipment in the station is taken as the re-search object, and the common vibration causes and vibration reduction measures are summa-rized and analyzed. The modal rules of common u-shaped pipes in the station are explored, and the main conclusions are drawn that the natural frequency is positively correlated with pipe di-ameter and radius of curvature, and negatively correlated with wall thickness, medium propor-tion and pipe length. In the end, the general steps of vibration reduction for this kind of pipeline are given, which can provide ideas for the exploration of vibration reduction schemes for the same type of pipeline.
