Random Vibration Analysis of Grid-Controlled Electron Gun in High Power TWT

Abstract:

The pre-stressed modal and random vibration of electron gun are calculated by finite element software ANSYS Workbench. The results show that electron gun under the excitation of radial load (X direction) can be in danger of disable structure. Some measures can be taken to avoid electron gun failure due to resonance, such as replacing the materials, changing the structure of weak links and changing TWT installation to make external incentives along the axial direction (Y direction). The analysis results can provide effective reference and guidance for TWT development.
