Abstract

The invention aims to provide a double-barrel embedded hybrid electromagnetic energy feedback damper. The double-barrel embedded hybrid electromagnetic energy feedback damper comprises a piston rod, an upper end cover, an inner barrel, a coil, a cylinder body and a piston head, the inner barrel and the cylinder body are designed to be of an embedded structure, magnetorheological fluid is injected into the cylinder body, so that an annular magnetorheological fluid channel and a concave magnetorheological fluid channel are formed between the inner barrel and the cylinder body, the length of a damping channel is increased, the maximum damping value capable of being output is increased, and the adjustable range of damping force is enlarged. According to the double-cylinder embedded type hybrid electromagnetic energy feedback damper, an energy feedback type electromagnetic damper and a magnetorheological damper are organically combined, the problems that an existing electromagnetic energy feedback damping device is small in damping force maximum value, small in adjusting range and complex in structure are solved, and the double-cylinder embedded type hybrid electromagnetic energy feedback damper has the advantages of being large in amplitude modulation range, high in damping force maximum value and simple in structure.

Description

technical field [0001] The invention belongs to the field of vibration reduction in mechanical engineering, and in particular relates to a double-tube embedded hybrid electromagnetic energy feed damper. Background technique [0002] In recent years, the energy-feeding electromagnetic damper has become more and more mature in the field of vehicle vibration reduction. Due to the complexity and uncertainty of the vehicle's driving road surface, in order to achieve good driving stability of the vehicle, the damper must have sufficient damping force and Large adjustment range. The damping force of the traditional energy-feeding electromagnetic damper is mainly realized by using the ampere force generated by the relative motion between the conductor and the magnetic force line. Under the action of the magnetic field, the coil and the conductor shell of the damper simultaneously cut the magnetic field lines, thereby generating the feeding current and damping force. Therefore, for...
