Abstract：A semi-active hydraulic shock absorber was designed and manufactured, and its dynamic characteristics were measured using MTS831. A fluid-structure interaction (FSI) method was used to build the dynamic model of this absorber and calculate its dynamic characteristics. The comparison between the calculated data and the measured ones showed that the error between the damping force of the absorber measured and that calculated is less than 15%, so the correctness of the absorber’s dynamic model built with the FSI method is verified. The influences of the absorber’s parameters, such as, oil viscosity and diameter of damping orifice on its dynamic performances were also analyzed. The proposed modeling method and test one provided a reference for further studying semi-active hydraulic shock absorbers.

Key words： semi-active hydraulic shock absorber dynamic characteristics fluid-structure interaction (FSI) finite element analysis
