Abstract:

Active mounting plate is in the state of vibration when it is working.Violent vibration would cause structure damage of active mounting plate and shorten its service life.So it is important to conduct vibration test on active mounting plate.Test method is designed in this paper and the vibration experiment is done of a certain type of radar active mounting plate.The comparison charts of feature level curves in the directions of X,Y,Z between the first and last test are given.Test results are analyzed and the structure design of the active mounting plate is evaluated.

Key words: vibration test;active mounting plate;feature level;structure design;evaluate
