Abstract:
Based on the integrating multi-objective optimization procedure, the improve design of a honeycomb structure under the impact load and free vibration analysis is investigated in this article. Using uniform design of experiment, a group of simulation experiments is generated. Apply the finite element analysis software, the maximum displacement and first-order nature frequency of the honeycomb structure are determined for the ASTM testing and free vibration simulations, respectively. Kriging interpolation is utilized to build two surrogate models that correspond to the maximum displacement and first-order nature frequency via the numerical results in the uniform design. In order to satisfy the minimized characteristic for the maximum displacement and the maximized characteristic for the first-order nature frequency, the genetic algorithm, grey relational analysis and entropy weighting analysis are used to resolve this multi-objective optimization problem. Compared with the original design, the optimal design induces 27.33% and 15.87% improvements for ASTM D7766 testing simulation and free vibration analysis, respectively. Consequently, the stronger and demanding honeycomb structure is developed by the innovative multi-objective optimization technique.
