A structural analysis model of the wing based on its physical characteristics is required for evaluating the influence of structure variations on the mechanics and aeroelasticity of the wing in the preliminary stage of wing design. Based on the relevant research on modeling the typical components of a multi-lattice missile wing which is comprised of spar/rib webs and skin. The modeling capability of equivalent plate model is developed to simulate caps and rods which are common in aircraft wings. Stiffness values of springs used to simulate the boundary conditions are discussed in detail, and the reasonable selection range is suggested. Some typical numerical results are presented from application of the model to the static analysis, dynamic analysis, static aeroelasticity and flutter analysis of a wing-box and a wing. Comparison of these results with the corresponding results from a finite element analysis indicates that good agreement is obtained, but the equivalent plate analysis is more efficient. The equivalent plate model can be used as an efficient model for quick analysis in the early design stage of lifting surfaces.
