在大量试验的基础上 ,用多元统计回归方法对 11炉冷轧钢板的基本成形性能与模拟成形性能试验数据进行了回归分析和相关性研究。结果表明 ,各模拟性能指标与基本性能之间有着较好的对应关系。有的模拟成形性能指标甚至与基本性能之间存在着较强的相关性。全相关性系数达 0 .95以上。
On the basis of a large number of experiments, the regression analysis and correlation of the basic formability and the test data of the formability of 11 cold-rolled steel plates were conducted by multivariate regression analysis. The results show that there is a good correspondence between each simulation performance index and the basic performance. Some simulation performance indicators even with the basic performance there is a strong correlation between. Full correlation coefficient of more than 0.95.
