Abstract：The math model of electromagnet is built, and the relationship between voltage and electromagnetic force is obtained. The dry friction force is controlled by adjusting the electromagnectic force that is applied to the interfaces, and a new semi-active control dry friction damper is designed based on this idea. According to the optimal shock isolation theory, a vibration and shock isolation system is designed, that is composed of semi-active control dry friction damper and a vibration isolator. Based on PID controlling, the performance of shock isolation can be improved greatly while assuming the performance of vibration isolation. The results of shock response and limiting performance analysis show: since the vibration isolation system is redesinged for shock isolation, the semi-active control shock isolator can get much more excellent performance than that of conventional one.
