인장시험과 유한요소해석을 통한 농업용 트랙터 보호구조물용 강재의 물성치 결정을 위한 연구 Determination of the Properties of Structural Steel for Agricultural Tractor Roll-over Protective Structure by Tensile Test and Finite Element Analysis
pp.808-817
This study was carried out to standardize the material properties of roll-over protective structure (ROPS) for agricultural tractor. The material properties which were obtained from stress-strain curve, a result of tensile test stress, were used to apply to the virtual test and varied from one production lot to the other and from one manufacturer to the other. And the finite element analysis was performed on the ROPS according to the OECD code. The results show that the load-displacement curves of virtual test were approximately equal to the actual test curves. The manufacturer or lot has been shown to have little effect on the properties of the material. Therefore, it is expected that the representative values that can be used in the finite element analysis can be determined by averaging the property values.
