基于拓扑优化的负泊松比防爆构型设计
Design of Blast-resistant Configurations with Negative Poisson's Ratio Based on Topology Optimization
摘要
Abstract
To enhance the blast resistance of military vehicles and mitigate the threat to the occupant compartment during explosions,research was conducted on protective structures with negative Poisson's ratio.The topology optimization method was employed,with the relative density of the material design domain elements as design variables and the minimization of Poisson's ratio as the objective,so as to obtain negative Poisson's ratio unit cells with different volume fractions.Core layers of different alumi-num alloys with negative Poisson's ratio were designed using an arraying method.Through simulations,the deflections of the front and rear panels and the overall energy absorption under various TNT equiva-lent explosions were analyzed.The results show that compared to the classical CS structure,the SXS structure reduces the back panel deflection of the sandwich structure by 19.43%and improves the ener-gy absorption capacity by 12.15%.关键词
