Vibration test is to assess the vibration mechanical properties of the specimens by reproducing the vibration environment under actual conditions.Compared to the traditional single-axis vibration test system,the three-axis vibration test system can provide highly accurate simulation of vibration environment,without under or over test.This paper analysis the three-axis vibration test system and control technology,and the design and optimization of the system and control strategy are as followings:(1)Three-ax...
