摘要：

In the process of working, travelling wave tube (TWT) produces high temperature which leads to thermal stress and also bears mechanical vibration. In this paper, thermal analysis, thermal stress analysis and modal analysis on TWT have been done by ANSYS Workbench, and the first six order modal frequencies and modal shapes are obtained. According to the vibration characteristics of TWT in working conditions as well as non-working conditions, the affection of temperature on the vibration characteristics of TWT have been analyzed.
