This paper introduces the working principles of a new electrorheological shock absorber which is developed on the basis of electrorheological technology and sets up the theory model for the new ERF shock absorber. It describes the relationship between electric field and resistance force of ERF shock absorber. The resistance force is composed of two parts: one is related with viscosity and another one is with dynamic yield shear stress. Therefore, On the basis of research on the nationalization of electrorhe -ological fluid, careful attention must be paid to the mechanical design of the electrorheological clique and in order to achieve the required range of the vehicle damping force. Experiments are made to support the theoretical studies. On the basis of the matrix theory, combined with experiments date, the inverse calcula -tion of the outer performance of ERF shock absorbers are made. It is meaningful for practical application.
