摘要：
A linear spring element was added to Bingham viscoplastic model to describe the viscoelastic plasticity of MR fluid in order to establish an accurate model for damper output. The above model was introduced into the multi-field coupling simulation by taking a shear and valve type magnetorheological (MR) damper with two-way push-over bar as the research object. The non-uniform dynamic magnetic field obtained by the magnetic field simulation was used to obtain the apparent viscosity distribution of MR fluid. Then the dynamic characteristics of the damper under different input excitation and current were obtained by post-processing. Results show that the simulation model of MR damper based on the series constitutive model is better consistent with the test results than the parallel constitutive model. The influence of each structural parameter on the damper magnetic field, the damper output and its adjustable range was analyzed according to the theory and simulation. The sensitivity of each parameter to the damper output was calculated. Results show that the gap of damper and piston diameter have great influence on the output of the damper, among which the piston diameter has the greatest influence, and the peak sensitivity index and average sensitivity index are 84.66% and 94.51 N respectively.
