流体诱发热电偶套管振动损坏分析

Analysis on the Damage by Fluid-induced Vibration of the Thermocouple Tube

本文简单介绍了流体诱发旋涡脱落导致工程结构振动的机理,分析了用于测量流体温度的热电偶套管断裂的原因,并提出了防止热电偶套管振动断裂的预防措施。

In this paper, the mechamism of flow-induced vortex shedding that results in engineering structure vibration is briefly introduced, so, the causes of breakage of the thermocouple tube are analysed and measures of preventing breakage due to vibration of the thermocouple tube are proposed.
