The Analysis and Solution Measures of Signal Interference in Vibration Table
Aiming at the problem that the vibration table cannot run normally due to the effect of interference sig-nals,this paper puts forward a way to add an isolating transformer and reduce the gain of the power amplifier be-tween the vibration controller and the power amplifier,so as to realize the vibration curve in the whole frequency band without interruption and ensure that the vibration test reaches the specified level.The test shows that the am-plifier can make the curve exceed the upper alarm limit at the low energy level,but not exceed the upper interrupt limit,and the test can run normally.The transformer can make the vibration curve normal at any energy level vibra-tion,and the two methods are reliable.
