Design and Experimental Study of the Vibration Control Device for Large Spatial Structure

Abstract:

According to active vibration control of the large spatial structure, a vibration control device called giant magnetostrictive material actuator was designed which could convert electromagnetic energy into mechanical energy. This device take giant magnetostrictive material as the core component and make full use of its magnetic properties like big force output, fast response, high reliability and low driving voltage. Then its principle and design method was analyzed, and output performance tests were done. The results show that this device have good magnetic circuit structure, high efficiency of energy conversion, and could output larger force and displacement under the drive current with linear relationship sensitively, and lay a good foundation for its application in the large spatial structure.
