Nonlinear model identification of a shock absorber dynamics

The paper discusses on the technique of modeling a nonlinear dynamics of a commercially available automotive shock absorber. The damper was tested on the damper test bench to obtain its dynamic characteristics. The characteristics include the force-displacement and the force-velocity diagrams. From...
