  • Because of the low efficiency on the classical multidiscipline design feasible(MDF), the strategy of the MDF improved by variable complex method was studied. Considering comprehensively the optimization accuracy and efficiency for the turbine shroud, the response surface method representing the high precise analysis simplified the calculation difficulty and then improved the optimization efficiency; by reasonaby introducing variable complex method, the double-loop optimization strategy periodically employed the high precision analysis and updated response surface equation to ensure precision. The turbine shroud multidisciplinary design optimization (MDO) with double-loop shows that this optimization object reduces by 1.4% obviously than that of classical MDF(0.97%), and it totally costs 2h39min equivalently to 1/3 of that of classical MDF.
