고속전철용 알루미늄합금 감속기 케이스의 열변형에 대한 구조해석 = Structural Analysis of Thermal Expansion of Aluminum Alloy Gearbox Case of High Speed Train

다국어 초록 (Multilingual Abstract)

For weight reduction of the gearbox of power bogie of high speed train, aluminum alloy is recommended for the material of the gerabox case. In this paper, three model(Steel G/B Case-Steel BRG. Case[model-S], Aluminum G/B Case-Aluminum BRG. Case[model-A], Aluminum G/B Case-Steel BRG. Case[model-AS]) were compared to each other in the view of thermal expansion. The evaluation of the internal load, thermal expansion deformation and lug analysis were executed. It results that the "model-A" is excessively deformed and fail in the bolt hole of bearing case. Material change of the bearing case to steel(model-AS) is effective to restrain the deformation of the inner radius of the bearing case and to prevent the failure of that.
