Tube trailer for high pressure vessel(typeⅠ) rack module is widely used to apply compressed natural gas(CNG) to bus because infrastructure of
natural pressure gas is revitalized. But recently, due to the needs for weight lightening and increasing inner capacity, rack module for type Ⅱ
CNG high pressure vessel is being commercialized. Fundamental structure of type Ⅱ rack module system is similar to that of typeⅠ rack module
system, which is considered only the total weight(about 26 tons) of typeⅠ rack module and fully charged vessels with CNG, so the type Ⅱ rack
module system is safe about self-weight. But the study considers the effect of vibration caused by forced power that occurs at outside and inside of vehicle and that arise from non smooth road surface and change of engine torque in transporting of high pressure vessels by rack module, preventing damage of rack module, destruction of high pressure vessels and gas leak accident duo to resonance phenomenon in advance. Therefore, to load typeⅠ and type Ⅱ pressure vessels for common use, in this study carry out vibration analysis according to location, shapes, numbers of beams in the environment and optimal design for minimizing the use of materials when outside harmonic force(4G) occurs. Finite element analysis(FEA) based on theoretical analysis is verified.
