摘要

以HMC—1022磁敏元件为基础

开发了二维弱磁检测仪器

利用自行设计的简易标定系统

测定了主要技术指标。选用拉伸后的A3钢试件进行检测

将结果和俄罗斯的TSC—1M—4型磁记忆检测仪检测结果进行了对比

二者的曲线变化规律基本相同。用Matlab软件画出检测结果立体图

在图形中可以准确地找到已知缺陷的位置。

Abstract

A two-dimensional low intensity field detecting instrument is developed based on the magnetism sensor HMC—1022

and its main technology index is tested by using a simple self-made calibration system.In the tension experiment of A3 steel

the sample is tested with both the developed instrument and Russian TSC—1M—4 magnetic memory testing instrument.Compared the testing results

it is found that the change rule of two curves is alike.The testing result is drawn solfware by using Matlab to a three-dimensional graph

and the self-made defect is exactly found in the graph.
