Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] As shown in the figure, a self-powered magneto-rheological damper includes a hollow piston rod 8, a magnetorheological damper system and an energy recovery system, and the energy recovery system includes an induction coil sleeve 13 fixed inside the piston rod The magnetic ring shaft 2 is arranged in the induction coil sleeve, and the external impact suffered by the piston rod 8 makes the magnetic ring shaft 2 and the induction coil sleeve 13 move relative to each other to generate magnetic induction line cutting and then generate an induced current to provide working power for the magneto-rheological damper system .

[0018] The magneto-rheological fluid damper system includes a left piston 6, a right piston 16 and a coil piston 14, and the left piston 6, the right piston 16 and the coil piston 14 are jointly installed on the p...

Abstract

The invention relates to a self-energy-supply magnetorheological damper and a working method thereof. The damper comprises a hollow piston rod, a magnetorheological damper system and an energy recycling system; the energy recycling system comprises an induction coil sleeve fixedly arranged in the piston rod; a magnetic ring shaft is arranged in the induction coil sleeve; and the external impactingborne by the piston rod makes the magnetic ring shaft and the induction coil sleeve relatively move to generate magnetic induction line cutting so as to generate induction current to be provided fora work power source for the magnetorheological damper system. According to the self-energy-supply magnetorheological damper, external power input is not needed, the self-energy-supply magnetorheological damper can be applied to a place without an external connection power source, the structure is simple, and adaptability is high.

Description

technical field [0001] The invention belongs to the field of magnetorheological dampers, and in particular relates to a magnetorheological damper in a self-powered form and a working method thereof. Background technique [0002] A damper is a device that provides resistance to movement and consumes movement energy. The working principle of the damper is to generate a reaction force that attenuates the external force, called the damping force (or shock absorption force), to delay the attenuation of the motion state. The magnetorheological damper is a new type of damper developed in recent years. Due to its advantages of low energy consumption, large output, and fast response, the magnetorheological damper has become a new generation of high-performance vibration damping device for structural vibration control. At present, magnetorheological fluid dampers have entered the stage of engineering application at home and abroad, mainly in the fields of construction, machinery and ...
