摘　　要：运用改进单纯形法，通过调整有关参数，对钢的硬度与强度换算公式进行优化设计，得到换算精度更高的换算公式：σｂ＝２０８．９６＋４３．４８ＨＲＣ－１．１８ＨＲＣ２＋ＨＲＣ３／５４．５３，式中ＨＲＣ为洛氏Ｃ级硬度值．Through optimizing the related parameters by modified simplex method, an optimizing conversion formula between hardness and strength for steels has been obtained, and the accurate conversion formula can be described as: sigma (b)=208.96+43.48HRC-1.18HRC(2)+HRC3/54.53, in which HRC is hardness value of Rockwell in grade C.

关 键 词：换算公式 改进单纯形法 优化设计
