To solve the problems of large workload and long calculation period on isolator stiffness optimization with finite element method for a two-stage vibration isolation system where the flexible effects of intermediate mass must be considered; a method using the dynamic method to optimize isolator stiffness and finite element model was proposed; and its effectiveness was evaluated by the experiment. According to the structural parameters of two-stage vibration isolation system; a decoupling optimization program was compiled and optimized results were obtained from various isolator stiffness schemes; Forced vibration calculation of the system's finite element model was carried out using the optimized results in each stiffness scheme; unit's vibration intensity and the sum of support reaction at the position of secondary isolator were calculated. The trends were consistent with the calculation results using the dynamic method. Experiment of diesel generator set was carried out according to the optimal stiffness scheme. Results showed that unit's vibration intensity and sum of support reaction from finite element calculation were consistent with the experimental results; which verified the correctness of this method;
