The working principle of a new type of electro-hydraulic fluid damper-electrorheological valve external shock absorber is expounded, and its theoretical model is established.It is described that the damping force of the new electrorheological fluid absorber The relationship between the electric field.The experiment of the shock absorber proved the correctness of the theoretical analysis.This paper used the matrix theory and the MATLAB software to reverse the external characteristics of ERF absorber based on the experimental data, The best fitting curves and formulas of the experimental data for the external characteristics of electrohydrodynamic fluid shock absorber were obtained, which laid the foundation for the design of the semi-active suspension for electrohydrodynamic fluid damper.
