Abstract

In this paper, an efficient design method of sponge adapter is studied. The structural parameters of the adapter that satisfy general requirements are designed quickly. The discrete variable of adapter is transformed into continuous variable by using discrete mixed constraint method; the parameterized model is simplified by using rigid beam to simplify missile and nonlinear spring to simplify sponge rubber; the Lagrange multiplier method is improved, and the constrained optimization problem is transformed into unconstrained optimization problem by combining optimization strategy, and the discrete mixed constraint optimization mathematical model is optimized and the adapter structure parameters that meet the requirements are obtained. The optimized structure size can make the deformation of the front, middle and back of the adapter almost the same, and does not tilt when the missile is stored. This method can automatically find the optimal solution of the structure, and the designer only needs to select the structure size fast and reliably which is more similar to the actual working condition according to the actual engineering demand.

Key words： design of adapter; design of sponge layer; discrete optimization; parametric modeling; constrained optimization
