FEM analysis of the tank car for carrying hazardous materials

위험물 수송용 탱크화차에 대한 유한요소 해석

In these days, many kinds of tank car such as Oil tank car, Asphalt tank car, Sulfuric Acid tank car and Propylene tank car are used for carrying hazardous materials. Although they have a lot of dangerous possibilities when they meet with accidents examples of collisions and derailments there are not prescribed methods or standards for structural analysis using FEM. In this study, the structural stress analysis for an Asphalt tank car(Non-pressurized tank) and a Propylene tank car(Pressurized tank) was performed using the FEM refer to the test method in JIS E 7102(Design Methods for Tanks of Tank Cars). And then we suggested the tank car analysis procedures and considered the results.
