钢材含碳量的无损检测方法

The Study of Nondestructive Testing Methold for Carbon Content of Steels

提出了一种新的钢材含碳量无损检测方法,设计了可靠性较高的检测系统,以钢材的磁特性为基础,用Autolisp语言编制计算机接口软件,测绘出钢材的磁化曲线和磁滞回线,应用神经网络理论,建立含碳量和磁性特征量间的非线性映射,实现含碳量的智能化检测.

This papers proposes a nondestructive testing methold for the carbon content test of steel.A highly reliable test system is designed. Based on the magnetismed property of steel .Using Autolisp languagaahe computer interface software is worket out.Then.the magnetized curve and hysteresis loop are mapped.Employed neural network-the nonlinear mapping between carbon content and magnetism parameter are built up. The intelligency test is realised.
