Optimal Design of Periodic Honeycomb Plate with Unit Cell Structure Based on Genetic Algorithm

Abstract

Composite honeycomb sandwich plates have been widely used in aerospace, ships, construction bridges, machinery, stationery, and other industries. In order to improve the performance and configuration, taking the structural dynamic characteristics of periodic honeycomb plate as the research object, a structural optimization design method based on natural frequency and stiffness was proposed with the goal of weight reduction. The geometric parameters of the structure system were trained by the multiobjective optimization genetic algorithm (MOGA), and the Pareto optimal solution of variable combination was obtained. This paper presented a decoupling method for complex system optimization design based on dynamic performance from the perspective of basic unit, which could solve the coordination problem of vibration stability and weight reduction in periodic honeycomb plate structure optimization design. It has reference significance for the similar composite material frame base structure design.

In addition, a plate made of FGM material and subjected to NL thermal loading has been investigated in order to optimize it is parametric FV characterizations through implementing the FEM as well as the nature-based algorithms by Rout et al [246].…”
