Abstract

This paper investigates the performance of vibration isolation for single-wheel vehicle suspension model using the Electrorheological(ER) mount system. The main contribution of this paper is that the optimal damping coefficients of the ER mount are obtained by using H2 and control methods and some initial experiment is also conducted to verify the control method. The control technique of optimal electric field associated with the optimal damping coefficients for ER fluids in squeeze mode with sinusoidal and broadband vibration excitation is also presented in this work. Both of the theoretical derivation and experimental investigation are conducted in present study. In the theoretical derivation, the optimal damping coefficients of the fundamental ER squeeze mode and numerical simulations from model are presented. In the experimental work, the relation of damping coefficients and electric fields is obtained from preliminary experiments. The results indicate that the proposed control methods are effective in suppressing the sinusoidal and broadband vibration. The work presented in the paper is the first part of this study. Copyright
