英文摘要 | In this paper, we develop a prediction model of steel's tensile strength with the Brinell hardness acting as a leading indicator for a high temperature. The prediction model combines the first-order two variables grey differential equation model GM (1, 2) from grey system theory and Taylor approximation method from approximation optimization theory. We abbreviate the combined GM (1, 2) Taylor approximation model as T-GM (1, 2) model. This combined model can obtain the most optimal predicted value by multi-times approximate calculation. We verified the effectiveness of T-GM (1, 2) model, through using heat-treated steel's tensile strength for a higher temperature from the corresponding experimental data of Breinell hardness. The experimental results show that T-GM (1, 2) model has high predictable power for steel's tensile strength. |
