In order to analyze working performance of shock isolators for large-scale marine equipment under heavy shock load, a certain type of stiffness variable shock isolator was studied by conducting FEA calculation and shock experiments. Good agreement between the simulation and experiments proves the efficiency of calculation method. Results show that the shock isolator can provide alterable stiffness in axial compression, and absorb enough shock energy within restricted area to achieve shock isolation and elastic limit of equipment in harmony.
