摘要
基于有限元软件ANSYS平台,建立栅控电子枪有限元仿真模型,提取其固有频率及振型,进而与实测结果对比,检验模型的匹配度,并通过模型的修正以实现该模型和实际样品的仿真性,为进一步的动力学计算奠定基础。
Electron gun,as the core component of airborne or missile-borne traveling-wave-tube was discussed from the angle of vibration mechanics.By using the finite element analysis software ANSYS,the analytical model of the electron gun is established and updated.The numerical results are in good agreement with the results of modal tests.It is very important in optimal design of the electron gun.
