Abstract
Titanium alloy materials are widely used in the marine and aviation fields due to their excellent properties. The submersible sailing on the water surface is faster than underwater diving, so once an accident occurs, the consequences are unimaginable. Based on the failure criterion of the J-K model, this paper uses finite element simulation software to study the impact of impact velocity and impact angle on the collision response of a titanium alloy cylindrical pressure shell, providing a reference for the deep sea titanium alloy pressure shell.
Highlights
With the rapid development of today’s world economy, the resources on land have fallen far short of human development needs, and countries all over the world have set their sights on the vast ocean

Summary
With the rapid development of today’s world economy, the resources on land have fallen far short of human development needs, and countries all over the world have set their sights on the vast ocean. It is a strategic development base that integrates resources such as biological resources, energy, water resources, and metal resources It is a great power for human exploration and protection of rights and interests. Since the 1960s, some foreign scholars or scientific research institutions have conducted numerous simulation experiments of ship collisions. Li Liangwei and Du Jianye [6] used the ship’s scale model to analyze the impact of impact speed and impact angle on shipboard structure damage based on the collision test of the ship’s towing tank and the simulation of the ship collision scheme in the marine environment. Titanium alloy has light weight, high specific strength, non-magnetic corrosion resistance and good heat resistance and low temperature resistance [8]
