| Abstract: | The slow-wave structure is one of the core components of a traveling wave tube. In order to evaluate the slow-wave structure＇ s vibration reliability, the finite element analysis is integrated with the simplified mathematical model to obtain the natural frequencies and mode shapes of the slow-wave structure. The relationship between the structures and the electrical properties as well as the intrinsic link formula of the natural vibration frequency is examined. After a comparative analysis of the relationships, the design for the structural optimization is provided to improve the its anti-vibration performance. |
