摘要
管道振动问题严重影响压缩机运行的可靠性和安全性。针对某公司气体压缩机出现的管道振动问题进行原因分析并进行了改进方案的优化。利用LMS virtual lab声学分析软件对模型进行声模态分析,ANSYS Workbench有限元分析软件进行结构模态分析。通过分析结果,确定了管道振动的主因,提出增设管夹的解决方案,并对比不同位置约束对管道振动的影响,优化了管夹的约束位置。现场结果证明增设管夹约束的改进方案是有效可行的。
Vibration of piping will seriously harm the reliability and safety of compressor in operation. With respect to the problem of vibration occurred in piping connected to one air compressor, the cause was analyzed and the operation scheme was optimized in this article. By using LMS virtual lab software, acoustic analysis of the model was carried out, and then by using ANSYS Workbench, structural modal analysis was carried out. From the results of the analysis, the main cause of vibration was determined. The measure of increasing pipe clams was proposed, and the clamps were located through the comparison for their effects to piping vibration. It has been proved that this measure is feasible and effective.
