本文使用了一台高时间分辨率的红外热象仪和一台孔径为20毫米的快速红外探测器,监测高速旋转弯曲疲劳样品的表面温度分布.确定了红外发射与局部疲劳损伤的关系,提出了一种新的疲劳损伤无损检测方法.
In this paper, a high-resolution infrared camera and a fast infrared detector with 20 mm aperture were used to monitor the surface temperature distribution of high-speed rotating bending fatigue specimens.The relationship between infrared emission and local fatigue damage A New Method for Nondestructive Testing of Fatigue Damage.
