Abstract: A twin-tube hydraulic shock absorber F-V model is proposed based on structure parameters. First, a finite element model of the shock absorber rebound valve plate is established, and the load versus valve deflection curve is obtained with the model. The relationship between flow rate and pressure variation is then calculated. Then, this curve is integrated into the shock absorber model. The comparison between the model output and experiment data demonstrates the high accuracy of the proposed model. Finally the influence of the structure parameters of the rebound valve on the damping performance is analyzed through simulation.

Key words: vehicle engineering, valve plate deflection, finite element method(FEM) modeling, shock absorber
