자동차 헤드와 블록의 내구에 대한 전산 해석 연구 = A Computational Study on Thermo-mechanical Fatigue of Head and Block Compound

다국어 초록 (Multilingual Abstract)

In the engines of automobiles, knowledge on the thermo-elasticity a priori is very informative in the design stage. Especially, increasing demands on engine performance and fuel economy have resulted in progressively higher loadings on internal components of combustion engines. Therefore the durability assessment should be requested in the cylinder head and block design. In this study, an efficient and reliable analysis technique for the cylinder head, gasket and block compound by using computer modeling and numerical method was described. Commercial software GT Power<SUP>TM</SUP> and Fluent<SUP>TM</SUP> were used to find the gas side and coolant side thermal loading condition. ABAQUS<SUP>TM</SUP> software was followed to predict the temperature and stress of the engine with utilization of estimated coefficients. FE-Fatigue<SUP>TM</SUP> was used for fatigue safety factor.
