摘要
可用于汽车结构的新一代钢种日益增多，由于材料的发展，材料的选择在设计和制造过程中都变得非常重要。本研究确定了汽车工业中使用的高强度低合金(HSLA)、双相(DP)、三相(TRIP)和复杂相(CP)钢板材料的抗拉强度、成形性、焊缝可承受载荷、疲劳应力、耐蚀性和价格标准数据，并采用MOORA (Multi Objective Optimization on Basis of Ratio Analysis)比率法对材料选择进行了研究。根据MOORA比值法选择DP级钢板材料是最优选择。
An application for the selection of steel sheet materials used in automotive construction with the MOORA method
The new generation of steel grades that can be used in automotive construction is increasing day by day and the material selection becomes very important both in the design and manufacturing processes due to the development in the materials. In this study, data on tensile strength, formability, load that weld joints can bear, fatigue stress, corrosion resistance and price criteria of high strength low alloy (HSLA), dual phase (DP), three phase (TRIP) and complex phase (CP) steel sheet materials used in the automotive industry were determined and a study was conducted for the material selection using the MOORA (Multi Objective Optimization on the Basis of Ratio Analysis) ratio approach. It was concluded that the selection of DP grade steel sheet material according to the MOORA ratio approach among the materials used in the study would be the optimum choice.
