Abstract :
A new innovative Hydro-pneumatic Semi-active Resettable Device by using MR-Fluid (MR-HSRD) is introduced for vibration suppression of structures. The novel device consists of a cylinder-piston system with control valve and magneto-rheological valve (MR-valve) mounted on a bypass pipe connecting two sides of the cylinder. The MR-HSRD is set by changing the stiffness and the damping of the device independently. Moreover, the hysteresis behavior can be adjusted by using different control logics for control valve. A mathematical model is presented for behavior of the device. The experimental results of MR-HSRD under cyclic and static loadings are presented and are compared with the mathematical models.
