The Random Vibration Analysis of Electron Gun Based on Finite Element Method

As an important part of microwave tube, the reliability and stability of electron gun has always attracted more and more attentions of researchers. Because the working environment of microwave tube is very harsh, such as vibration, collision and impact. Therefore, numerical simulation technique is a necessary for researchers to optimize structures to avoid deformation and fatigue fracture in severe working conditions. In this paper, we developed the Mechanics Simulator module (MCS) of microwave tube mechanics simulation software by using finite element method. To validate MCS, numerical results for a simplified electron gun are shown compared with ANSYS.
