- Recently, hydrogen energy has been widely used because of strict regulations on greenhouse gas emissions. For using the hydrogen
energy, it is required to supply hydrogen through a tube trailer. However hydrogen tube trailer can have excessive load problems during
transportation due to reasons such as road shape and driving method, which may lead a risk of hydrogen leakage. So it is necessary to
secure a high level of safety. The purpose of this study is to evaluate structural safety for the conservative design of hydrogen tube trailer.
First, finite element(FE) modeling of the designed hydrogen tube trailer was performed. After that, safety evaluation method was
established through static structural simulation based on the standard GC207 conditions. In addition, effectiveness of the designed model
was confirmed through the results of the structural safety evaluation. Finally, driving simulation was used to derive acceleration graph
according to time, which was considered as a dynamic property for the evaluation of conservative tube trailer safety evaluation. And
dynamic structural simulation was conducted as a condition for actual transportation of tube trailer by applying dynamic properties. As a
results, conservative safety was evaluated through dynamic structural simulation and the safety of hydrogen tube trailer was confirmed
through satisfaction of the safety rate.
