수소차량용 연료공급 파이프의 동적 안정성 해석 = Stability of Dynamic Behavior of Fuel Supply Pipe for Hydrogen Fueled Vehicle

다국어 초록 (Multilingual Abstract)

The fuel supply pipe connected to the hydrogen fueled vehicle hydrogen tank is very complicated. Therefore, the fixed portion of the pipe should be determined according to the external vibration. In particular, in order to avoid the resonance frequency range of the hydrogen fueled vehicle, it is necessary to examine the vibration characteristics of the fuel supply pipe and the stress concentration generation part for each frequency. Therefore, the purpose of this study is to understand the resonance potential for the natural frequency of the fuel supply pipe for hydrogen fueled vehicles and the excitation force(vibration of the motor etc.) applied to the external excitation frequency range(1-40Hz). Vibration characteristics were analyzed using the finite element method(FEM) to secure basic data for future seismic vibration tests of fuel supply pipes and to evaluate the safety of fuel supply pipe system.
