Abstract

As an important structure connecting the hull to the ship's equipment, whether the base can play a protective role when the equipment is subjected to impact loads is the key to improving the combat effectiveness and vitality of the ship. In order to improve the impact resistance of shipboard equipment, this paper designs a novel negative Poisson's ratio structure, calculates its stress-strain curve and specific energy absorption curve, designs the base of shipboard equipment based on the novel negative Poisson's ratio structure, uses the numerical simulation method to carry out the static analysis and modal analysis of the base, and studies the influence of the negative Poisson's ratio structure parameters on the impact resistance of the base. The results show that the novel negative Poisson's ratio structure has better energy absorption capacity and the acceleration response of the base decreases with decreasing cell length.
