Abstract
The present paper considers the efficiency of modelling experimental pressureflowrate characteristics of an MR throttle valve by a technique, according to which hydraulic resistance coefficient of a valve is determined as a function of Reynolds and Hedstrdm numbers. In predictions, an MR fluid is characterised by density, out-of-field viscosity and yield stress. It is shown that the hydraulic characteristics of a valve predicted by Hedstrom's technique are fit to the experimental ones over the entire range of magnetic field and MR fluid flowrate. The procedure for prediction of valve parameters that allows a damper design to be optimised is presented.Keywords
