A Multi-Azis Vibration Fizture Based on Electromagnetic Shaker

摘要：

This paper introduces a kind of vibration fixture which can support products undergo vibration simultaneously along three mutually orthogonal axes on the electromagnetic shaker, and the ratio of the vibration values along three product installation directions is coincident with the theoretical set value.Moreover, the vibration feature and design scheme of this multi-axis vibration fixture arc discussed.It is found that using this multi-axis vibration fixture on the electromagnetic shaker can avoid the problems currently existing in the vibration testing using the pneumatic hammer shaker and the electromagnetic shaker,such as random vibration frequency spectrum of the pneumatic hammer shaker is uncontrollable and the electromagnetic shaker can only perform uniaxial vibration testing,etc.Finally, the vibration feature of the multi-axis vibration fixture is verified by a testing.
