Abstract：Recently, effective vibration isolation design method has not been formed yet for the powerpack two-stage isolation system attached with a subsystem and the researchis aimed to tackle this situation. Atwo-step optimization methodwas put forward, in which the first and second isolator stiffness was firstly obtainedby optimizing the main system, secondly the subsystem was used as an absorber of the main system and its isolator stiffness was optimized according to H∞ criterion. Then the method was applied in the optimizationdesign of a certain DMU powerpack.Based on the optimized parameters the experiment of isolation performanceof the powerpack was conducted to verify the method. The results show that the optimized powerpacktwo-stagevibration isolation system has excellent vibration isolation performance in both conventional condition and shutdown condition, and so, the method is effective to design the isolation system.
