摘要
建立行波管模型并进行模态分析,提取行波管振动模态参数。从模态结果可知,2000 Hz以内的振动薄弱部位落在电子枪部位,行波管整管模型的固有频率和振型与管子单个部件的固有振动特性相对应。本文应用VC++软件对ANSYS软件进行了二次开发,形成行波管振动特性模拟仿真软件,使用该软件可以快捷实现行波管及部件的参数优化设计。
The finite element model of traveling wave tube was established and vibration parameters of traveling wave tube were extracted.From the results we can see weak parts of model vibration the falling within the electron gun.The entire tube and submodel of the natural frequencies and mode shape were matched.In this paper,the secondary system development of vibration characteristics of simulation by using VC＋＋ and ANSYS software had made,user can quickly achieve the parameter optimization of TWT.
