Finite element numerical simulation of hydrogen storage vessel under dynamic load impact

With the development of global society and the progress of technology, hydrogen energy is gradually becoming an emerging clean energy source. As a special high-pressure container for storing hydrogen, damage to the hydrogen storage vessel under the impact of dynamic load can cause serious accidents. In order to study the mechanical property changes of hydrogen storage vessel under dynamic load, this paper adopts the equivalent static method to numerically simulate the steel hydrogen storage vessel and analyze the effects of load size and impact location on the stress-strain of hydrogen storage vessel under dynamic load impact, so as to provide theoretical basis for the analysis, evaluation and design of hydrogen storage vessel's crashworthiness.
