框架结构顶层振动测试与分析

加氢车间的压缩机振动诱发框架结构振动,造成无法继续施工。为了确定框架结构产生晃动的原因,对其进行了现场振动测试,并利用DASP6.53数据分析软件包进行了频谱分析。结果表明是压缩机转频引起框架结构共振。在此基础上,提出了改变振源频率或框架结构固有频率的解决方案,为下一步安全施工提供了理论保障。

Vibration Test and Analysis of Top Floor on Frame Structure

In hydrogenation plant there exist vibration of compressor and induced vibration of frame structure. In order to determine the cause of the severe vibration of the frame structure, the vibration data are measured and analyzed with the aid of the data software package DASP6.53. It is concluded that source of heavier vibration is due to resonance between the compressor and the frame structure, which cause shutdown. Based on the research, some proposals are put forward to guarantee a safe further con-struction.
