【Abstract】 The structural mechanics of grid-controlled electron gun in a travelling wave tube is simulated,as well as the intrinsic mode of the structure and the random response characteristics under the condition of a power spectral density are calculated.The simulation results are analyzed and used to avoid sympathetic vibration in design of highly reliable grid-controlled electron gun in a travelling wave tube.The tube successfully passed the random vibration test,and the test results meet the requirements of military standard.更多还原
