The shock resistance performance of the vi ration isolation system w ill then e affected. By using the sofwt areANSYS, the fin ite elementmodel of the vi ration isolation system is u iltw ith the diesel engine offsetting in longitud inal and lateral direction separately. The d isp lacem ent and acceleration response of the device is calculatedw ith a shock exerting on the fundation of the vi ration isolation system. Som e sign if-i cant conclusions are o tained wh ich are valua le to the engineering app lication.
