阐述脉冲涡流的基本原理,并介绍TZ-2W型脉冲涡流检测仪的研制内容和主要功能。在机车轮心检测应用试验中,脉冲涡流检测可以有效发现表面裂纹等缺陷,并且能对机车轮心产生破坏的可能性进行预测。脉冲涡流检测技术有望成为在役机车轮心不动车探伤检测早期失效或疲劳裂损的有效手段。
Describes the basic principles of pulse eddy current, and introduces the TZ-2W pulse eddy current detector content and main functions. In the locomotive wheel center test application test, pulse eddy current testing can effectively detect defects such as surface cracks, and can predict the possibility of locomotive wheel center damage. Pulsed eddy current testing technology is expected to become an active means of detecting the early failure or fatigue cracking of wheel center locomotives in service.
