Abstract

Liquefied natural gas is used as fuel for public buses and trucks to reduce greenhouse gas emissions. The fuel container of a truck is exposed to the outside; hence, it is necessary to determine whether it is safe for a collision. Damage to materials caused by collision is considered critical not only in the automobile industry but also in various industries. In this study, the structural integrity of a pressure vessel was evaluated through crash tests and a numerical analysis model, to which the Johnson'“Cook model was applied. The crash tests were performed according to the test standards of Korea and the United States. A comparison between the numerical model results and experimental results for the head-on collision condition was performed to validate the numerical model. The established finite element model was used to evaluate the critical collision energy of the pressure vessel under various collision conditions. Based on this, the integrity of the pressure vessel was evaluated.
