Problems solved by technology

[0003] Existing magneto-rheological shock absorbers often adopt a single-piston structure, which has the disadvantages of a small adjustable range of damping force and a short piston stroke, which directly affects the performance of the shock absorber and severely restricts the application range of the magneto-rheological shock absorber.

Abstract

The invention aims to provide a bidirectional multi-piston hybrid magneto-rheological shock absorber. The shock absorber comprises a working cylinder, a piston rod I, a piston rod II, an electromagnetic piston I, an electromagnetic piston II, a floating piston, magnetorheological fluid, a coil, a permanent magnet ring, a spring I and a spring II, wherein the electromagnetic piston I, the floatingpiston and the electromagnetic piston II are sequentially arranged in the working cylinder from left to right, and the working cylinder is filled with the magnetorheological fluid. The magneto-rheological shock absorber has the advantages that the damping force of the magneto-rheological shock absorber is effectively increased, and working reliability and stability of a magneto-rheological dampingdevice are improved.

Description

technical field [0001] The invention belongs to the field of magnetorheological technology, and in particular relates to a two-way multi-piston hybrid magnetorheological shock absorber. Background technique [0002] Using magnetorheological dampers to control structural vibration is one of the research hotspots in vibration reduction technology that has emerged in recent years. It is a controllable damping device. The damping medium of its internal hydraulic cylinder is made of magnetorheological materials, mainly composed of micron-sized The soft magnetic particles of different sizes are mixed with the matrix and the stabilizer. The working principle is to adjust the current in the exciting coil to obtain a magnetic field of different strength, so that the flow characteristics of the magnetorheological material in the damping channel are changed, and this change is continuous. Reversible, that is, once the magnetic field is removed, it becomes a material that can flow again...
