Abstract: In order to ensure the accuracy of failure mechanism analysis for titanium alloy pressure vessels, this study proposes to use thermal coupling simulation for failure mechanism detection, and use micro analysis method and finite element software model analysis method to conduct pressure testing on TC18 titanium alloy pressure vessels. The entire experimental process was carried out using a JR-3DSS optical scanner to determine the surface condition of titanium alloy high-pressure containers, and the container performance was calculated using relevant public displays. Research has shown that the main reasons for the fracture of titanium alloy high-pressure vessels are corrosion and the formation of grooves in the weak positions of the vessels due to high-pressure gas impact. The interaction between impact load and corrosion highlights the fracture characteristics.
