【Abstract】 In order to predict the force-velocity behavior of a magnetorheological(MR) damper with a hole duct valve,a quasi-static axisymmetric model of was built based on the Herschel-Bulkley and Bingham models,the pressure gradient equation was derived. For the Herschel-Bulkley model,the pressure gradient equation was solved numerically,and for the Bingham model,the analytical solution of the pressure gradient equation was obtained by using the algebraic equation theory. An example of simulation was presented to predict the velocity profile of the MR fluid through the hole duct valve and the damping force.更多还原
