摘要：
A new disc type orifice magneto-rheological fluid damper(MRD) based on passive twin-tube hydraulic damper is designed, and its calculation model of the damping force is deduced through laminar flow model of Newton-fluid in disc type orifice and Bingham constitutive relation of Magneto-rheological fluid(MRF). The definition of adjustable multiple of damping force, which is one of the most important performance parameters of MRD, is put forward, and its formula is also deduced on the basis of the mechanical model. By analyzing various factors in the formula that influence the adjustable multiple of damping force, the way of increasing the adjustable multiple with constant damping force and zero magnetic-field intensity is obtained. At last, bench test of the designed MRD is carried out, and the correctness of the derived mechanical model is verified. The relation between the adjustable coefficient and the disc type orifice height is obtained through the analysis of the test data of MRDs with three different orifice heights. Additionally, the influence of fluid temperature rise in low-temperature MRD at different currents on the adjustable damping force is analyzed. © 2010 Journal of Mechanical Engineering.
