Abstract:
A single-cylinder magnetorheological damper was designed in this paper, and a single-cylinder mag¬netorheological damper damping force calculation method was proposed for the study of the damping characteristics of magnetorheological damper. Firstly, the damping force model of the single-cylinder mag¬netorheological damper was established; secondly, the magnetic domain model of the single-cylinder magne¬torheological damper was established, and the mag¬netic field distribution was obtained by using the sim¬ulation software; finally, the relationship between the magnetic flux density of the core inlet and outlet and the coil current was obtained through experiments. The calculation results show the variation rule between the coil current and the damping force under different motion rates of the core, and are compared with the experimental data. The relationship between the damping force and the movement rate of the core was also shown when the clearance between the core and the inner wall of the cylinder cylinder varies.
