Abstract
The high pressure vessels (type I) are widely used to refuel compressed natural gas (CNG) to vehicles in domestic regions because infrastructure of CNG is revitalized. But, due to a demand for pressure vessel with weight lighting and increase of inner capacity, rack module for the high-pressure vessel (type II) is being commercialized. Fundamental structure of the rack module for the vessel (type II) is similar to that of the vessel (type I), which has the total weight, about 26 tons; including 20 vessels fully charged with CNG. And vibration caused by non-smooth road surface and engine torque damages vessel and leads an accident involving a gas leak. For a common use of tube trailer with type I and type II vessels, this study carries out design of rack module by considering vibration and fatigue analysis for structural safety and minimization of materials according to location, the supporting shapes and the numbers of beams.
