摘      要：Optimal design of the tank has a significant effect on reducing the weight of a launch vehicle’s *** this paper,the key characteristics of a stiffened shell are identified from the design requirements,focusing on the influence of the internal pressure on the axial compression load-bearing *** computing method of the ultimate load of the stiffened shell,the parametric modeling method and the surrogate modeling technique for optimal design are *** optimization process applicable to the stiffened shell was developed and applied in the optimization work for the tanks of solid-liquid bundled launch vehicle,so a better weight reduction effect could be achieved.
