Energy reclaiming self-sensing magnetorheological damper

The present invention discloses a self-sensing energy reclaiming magnetorheological damper, wherein the damper comprises a magnetorheological pure shear magnetorheological damper, the mechanical energy into electrical energy and the feeding mechanism can a rotational speed sensor that pure shear magnetorheological damper using the ball screw mechanism converts linear magnetorheological damper piston linear motion into rotational motion, the effective use of the magnetorheological fluid operating modes shear mode, cutting disc is provided, the shear ring and the corresponding electromagnetic coil magnetically damper damping force steplessly controllable properties. The present invention uses a magneto-rheological fluid shear mode, and effectively improve the dynamic range of the damping ratio, the impact of high speed / low speed vibration control system having a more effective control of; the present invention have both power and performance feedback from the motion sensing performance, solve the problem of the energy supply semi-active MR damper and the control system and the problems due to the additional feedback sensor mounted state caused by the installation space, system weight, cost and reliability.
