A novel Magneto-rheological Fluid (MRF) shock absorber with annular channel with cascade coils and parallel micro-bypass, gas volume compensation using floating piston, was proposed to solve the problems of inadequate compensation of MRF shock absorber, and the non-smooth transition of damping force when the piston changes direction. Parameters of the Biplastic-Bingham constitutive model were identified by the test of MRF. The quasi-steady differential equations of MRF flow in the annular damping channel were established to obtain the relation between the flow getting through the piston and the pressure difference between the two chambers. The calculation method of MRF damping force was studied, which is in the interaction of throttling effect of the bypass and the guide slot, volume compensation with floating piston and the friction between parts of the shock absorber. A MRF shock absorber was designed and fabricated, according to the suspension technology requirements of a selected domestic automobile and its dynamometer characteristic was tested. The results indicate that the dynamometer card of the shock absorber is full, and the theoretical damping force of the shock absorber under various excitation current are accord with the test data.
