Abstract

In response to the problem of channel blockage caused by the extension of effective damping channels by multi-stage radial structures, combined with the strengthening effect characteristics of the magnetorheological fluid under compression, a radial wedge-shaped squeezed magnetorheological valve is designed without changing the basic structure and appearance dimensions. By defining the "wedge angle" and using differential thinking to divide the wedge damping channel into several microelements, a functional relationship between the microelement model and the "wedge angle" is established. And then the relationship between the "wedge angle" and the pressure drop inside wedge-shaped channels is derived based on the Herschel Bulkley (HB) constitutive model. Considering inertial effects and local losses, a general mechanical model of HB-Minor Losses-Inertia (HBMI) is constructed. Besides, the influence of "wedge angle" on the cross-sectional flow velocity, pressure gradient, and local loss of wedge-shaped channels is conducted. Further, a drop tower test system is build to conduct the dynamic behaviors of the wedge-shaped magnetorheological energy absorber (MREA) under different impact velocities and currents. Results show that the wedge-shaped MREA has good controllability when the "wedge angle" is set within Δδ=2 mm. Its dynamic range is 1.45，and the maximum buffer force is up to 236 kN．Comparing the test results with the theoretical model, it is found that the HBMI model can accurately predict the dynamic behavior of the radial wedge-shaped squeezed MREA under impact load.
