Abstract

Due to the problems of complex regulation, large mass, and poor adaptability, the traditional ship leak-plugging umbrella is often difficult to be effectively applied in the process of warship leak-plugging. In this paper, starting from the technical scheme and performance characteristics of naval leak plugging umbrella, a design of naval anti-umbrella plugging umbrella based on water-absorbing and expanding rubber material is proposed. Based on the good ductility and elasticity of the swollen rubber material after absorbing water, it achieves the anti-parachute coverage of the breach under the action of water pressure. Meanwhile, an axisymmetric non-linear finite element analysis model of the rubber plugging umbrella is established using ABAQUS to analyse the stress-strain state of the umbrella at different water depths. The results show that the new leak plugging umbrella has a reasonable design, high pressure strength and good sealing performance, which can significantly improve the ship's leak plugging capacity and has broad application value.
