N2 - Aiming at a composite flexible skin composed of zero Poisson's ratio honeycomb and elastic skin, a comprehensive optimization method was proposed. Firstly, the geometric parameters of flexible skin were taken as variables, and a parametric modeling method of flexible skin was designed; Secondly, an approximate model of the relationship between geometric parameters and mechanical properties of flexible skin was constructed based on the response surface method, and the accuracy of the approximate model was evaluated quantitatively; Finally, considering the in-plane strain, out-of-plane deflection, mass and other factors, a comprehensive optimization mathematical model is established by the weighting coefficient method, with the geometric parameters of the flexible skin as the optimization variables. Meanwhile the optimal configuration of the flexible skin structure was obtained by the genetic algorithm. This article constructs a finite element model of composite flexible skin and verifies the comprehensive optimization method. The results indicate that compared with the initial configuration, the optimized configuration has an in plane deformation capacity increase of 14.70%, an out of plane bearing capacity increase of 32.65%, and a structural mass reduction of 28.03%. This proves that the comprehensive optimization method proposed in this article has important guiding significance for the design of composite flexible skin.
