摘要:
为了实现全场多尺度变形测量,利用三轴电动平移台、4台高分辨率相机、3个不同放大倍数的远心镜头和1个显微镜头组成了多尺度二维数字图像相关测量系统,采用该测量装置可实现从宏观到微观尺度的变形测量.实验结果表明:通过置于高精度三维可控平移台上的二维数字图像相关测量装置,可实现任意微区的跟踪观测.经过标定的测量系统可以对观测区域实现测量尺度的任意切换,达到所需要的测量精度及观测要求.最后对贝氏体钢腐蚀后的表面纹理进行了数字图像相关测量.该测量系统对于裂纹尖端力学行为的研究具有很好的应用前景.
Abstract:
To realize multi-scale deformation measurement using digital image correlation(DIC), a multi-scale two-dimensional digital image correlation(DIC)system was introduced. The measurement device consists of an electric three-axis translation stage, four high-resolution CMOS cameras, three telecentric lens with different magnifications, and a microscope. Deformation measurements from macro to micro were performed by using the device. The measured results indicate that the system can be used for tracking the micro-region by precisely controlling the three-axis translation stage. After the system calibration, the measurement scale was changed for the arbitrary observation region to meet the requirements of the accuracy and the observation. Using the surface texture of bainitic steel after corrosion, the DIC measurement from macro to micro was achieved. Measurement results show that the system has good potential for studying of the mechanical behavior of the crack tip.
