Abstract
The invention discloses an engine magneto-rheological hydraulic mount method based on a circumferential and radial flowing mode. By means of the combination of a circumferential damping passageway and a radial damping passageway, the length of the damping passageways is increased in the limited structural size; the longer the damping passageways are, the larger the output damping force becomes; due to the fact that the amplitude of an engine is small, the maximum damping force can be increased by increasing the length of the damping passageways, and the adjustable range of the damping force can be widened; the width of the radial damping passageway is determined by the size of an insertion pin, and the width of the radial damping passageway can be changed by changing the size of the insertion pin; a liquid injection hole and an exhaust hole are formed in the middle of a reinforcing block, and therefore exhaust is more smooth in the liquid injection process, and liquid injection can be more convenient; a shell is made of magnetism isolation aluminum alloy material, and therefore magnetic flux leakage is weakened for a magnetic circuit when the engine works.
