구조해석을 통한 SUV 자동차용 연료탱크 구성부품의 영향성 평가에 대한 연구 Effect Study of SUV Automotive Fuel Tank Components by Structural Safety Simulation
pp.137-141
In this study, the design of fuel tanks for SUVs (sports utility vehicles) was dealt with through structural analysis. Fuel tank analysis was performed to evaluate safety, and improvement plans for weak areas were found and reflected in the design. In addition, strength analysis and pressure analysis were performed in parallel to solve the problem of oil leakage around the lower part of the fuel tank and the rear mounting that occurred during the endurance test, and the analysis results were reflected in the design. As a result of analysis through various design changes, it was possible to present an appropriate reinforcement flange shape. In addition, when the thickness of the fuel tank was changed from 1.0mm to 0.8mm, the stiffness of the fuel tank decreased by approximately 30%, and reinforcement was required.
