摘要

行波管是通信卫星的功率放大器。电子枪对空间行波管的寿命和可靠性起着至关重要的作用，本文利用COSMOS和ANSYS软件对空间行波管进行了三维热分析和结构分析。模拟了阴极、束聚焦电极和阳极等不同电极在轴向和径向上的膨胀情况。除此之外，还对电子枪装配进行了频率分析。给出了COSMOS和ANSYS计算结果的比较。

Thermal and structural analysis of electron gun for high efficiency space TWT

Travelling wave tubes (TWTs) are power amplifier for communication satellite. As the electron gun plays a significant role in determining the life and reliability of the space TWT, the same has been subjected for 3-dimensional thermal and structural analysis using FEA code COSMOS and ANSYS. Expansion in different electrodes like cathode, beam focus electrode (BFE) and anode in axial and radial direction has been simulated due to temperature distribution in the gun. In addition to the above, frequency analysis of electron gun assembly has also been carried out. A comparison of COSMOS and ANSYS results has been presented.
