Abstract: A 3D variable damping vibration isolator based on rubber friction and extrusion mechanism is composed of a base, an upper plate, a vibration isolation spring, “ ” shaped bolts, lock nuts, damped rubber blocks and a shell. The damped rubber blocks are vulcanized and bonded to the external vertical surfaces of vertical steel angles uniformly distributed on the base and are opposite to each other in pairs; the upper end of each “” shaped bolt is fixed to the upper plate by upper and lower (two) lock nuts, and cross bars at the lower end are squeezed by the damped rubber blocks on both sides; contact surfaces of the damped rubber blocks and the “” shaped bolts are flat-a design of variable cross-section. The vibration isolation spring is sheathed between the base and a lug boss in the center of the upper plate.
