Abstract: To optimise the working performance of magnetorheological damper, a new parallel gap magnetorheological damper is designed. The validity of the structural design is verified and guided by establishing a mathematical model of a parallel gap magnetorheological damper. The damper is designed using a check valve structure, which greatly reduces the installation space, reduces the transfer linkage, and improves the reliability of the damper. The newly-designed damper has many advantages, such as high efficiency, high sensitivity, no precipitation, good heat dissipation, greater damping force, and so on. The experimental and theoretical analysis results show that the performance of the parallel gap magnetorheological damper is excellent.
