Abstract: A JPZ three-axial iso-rogid isolator with damper is replaced by a three-axial isolator with damping spacer which is made by 9050 viscoelastic high damping material produced by our own country. When is is used in a 5.8kg electronic equipment its low resonant frequency is 45±3Hz, and its amplification ratio will be smaller than 3. When an excitation frequency greater than 67 Hz is used, this isolator will take isolation effect.
