Abstract

This paper deals with feature of the magnetostrictive actuator. The current-displacement hysteresis loop has been modeled mathematically. Based on the experimental data, this model has then been predigested into a linear one. And then several experiments have been carried on to validate this model. By putting the actuator into a certain testing platform, the correct results of the system which is excited by a single current input signal, a single mechanical input signal and the co current-mechanical signal have been achieved. Through a serial of given experiments by using diverse current and mechanical exciters, the actuator has been put into applications and the dynamic characteristics of the vibration responses of certain situations of the “electro-magneto-elastic integral system” has been gained. Based on all the study of the dynamic characteristic of the actuator’s vibration output, and from the aspect of minimizing the output displacement of the actuator, the method of vibration control has been carried on. We have measure to input a control current to make the vibration of mechanical exciting system lowest. This is the basis of designing a smart structure and carrying on vibration control.
