Description

technical field [0001] The invention belongs to the field of performance testing of intelligent materials, in particular to a shear performance testing device of a magnetorheological elastomer. Background technique [0002] Vibration isolation is a vibration control method that reduces the vibration of the target vibration reduction object by controlling the transmission of vibration, that is, reducing the vibration of the target vibration reduction object by adding a vibration isolator between the vibration source and the target vibration reduction object. From the perspective of vibration isolation methods, vibration isolation systems can be divided into passive vibration isolation, semi-active vibration isolation and active vibration isolation. Among them, semi-active vibration isolation has the advantages of both passive vibration isolation and active vibration isolation, and overcomes the disadvantages of weak adaptability of passive vibration isolation and high energy ...
