The invention discloses an
energy feedback type self-sensing
magnetorheological damper. The
energy feedback type self-sensing
magnetorheological damper is characterized by comprising a pure shearing type
magnetorheological damper body, an
energy feedback mechanism used for converting
mechanical energy into
electric energy, and a rotating speed sensor, the pure shearing type magnetorheological
damper body converts linear movement of a linear magnetorheological
damper piston rod into rotational movement by means of a
ball screw pair mechanism, the shearing mode which is one of the working
modes of magnetorheological liquid is effectively utilized, and stepless damping force
controllability of the magnetorheological
damper is achieved by arranging a shearing disc, a shearing ring and a corresponding
electromagnetic coil. According to the energy feedback type self-sensing magnetorheological damper, by means of the shearing mode of the magnetorheological liquid, the range of dynamic damping ratios is effectively widened, and a more effective control range is provided for a high-speed
impact and low-speed
vibration control system; both the
electric energy feedback performance and movement state self-sensing performance are realized,
energy supply of a semi-active magnetorheological damper and the
control system of the semi-active magnetorheological damper is achieved, and the problems, related to installation space,
system weight, cost and reliability, caused by additional installation of a state feedback sensor are solved.
