Abstract

The invention aims to provide a hybrid valve type magnetorheological damper. The hybrid valve type magnetorheological damper comprises a piston rod, a left end cover, a cylinder body, a piston head and a coil, a damping channel is formed between the piston head and the annular groove, and an embedded stepped damping channel is formed, so that the effective length of the damping channel is increased, the maximum value of damping force is increased, and the damping adjustable range is widened. A coil, a permanent magnet block and a spring structure are arranged in the cylinder body, so that a magnetic field still exists in zero current. The hybrid valve type magneto-rheological damper can solve the problem that an existing magneto-rheological damper is limited by power supply, and has the advantages of having an energy storage function and being large in damping force amplitude modulation range, simple in structure and high in stability.

Description

technical field [0001] The invention relates to the field of mechanical engineering vibration reduction, in particular to a hybrid valve type magnetorheological damper. Background technique [0002] In the traditional magnetorheological damper, the applied magnetic field is generated by the energized excitation coil wound on the conductive magnetic core, and the size of the excitation coil and the iron core is limited by the size of the magnetorheological damper cylinder. If the magnetic field is increased by increasing the number of coil turns, the size of the damper cylinder will be larger, the amount of magnetorheological fluid will be increased, and the cost of the damper will be increased. If the size of the cylinder is reduced, a large enough external magnetic field cannot be obtained, which in turn affects the maximum output and adjustable coefficient of the magnetorheological damper. This phenomenon is especially serious for small-sized magnetorheological dampers. ...
