RESPONSES OF A NEW ACTIVE VIBRATION ISOLATION SYSTEM TO RANDOM VIBRATIONS

The responses of the test mass of the new active vibration isolation s ystem incorporating a quasi-fixed reference system to two typical rand om vibrations such as Gaussian white noise and seismic noise in gravit ational experiments are presented. A conclusion is obtained that the i solation performance of the new active vibration isolation system from random vibrations is better than that of the traditional one.
