本条数据采用的设备为ZYGO公司生产的NewView9000型3D表面光学轮廓仪，放大倍数为10x，实验中的轴套的材料为GCr15。对实验之后的配合轴套内径表面进行测量，分别对两个接触边缘与接触面内部进行测量。测量表面形貌，确定表面裂纹萌生角度和萌生部位，以便与仿真结果进行对比。本文件夹为旋转次数为2×10⁵次的实验轴件的配合轴套内表面不同位置的形貌采集图片，2d为平面照片，3d为立体照片，origin为平面黑白照片，相对2d是为了方便观测。

The equipment used in this article is the NewView9000 3D surface optical profilometer produced by ZYGO Company, the magnification is 10x, and the material of the shaft sleeve in the experiment is GCr15. After the experiment, the inner diameter surface of the mating bushing was measured, and the inner of the two contact edges and the contact surface were respectively measured. The surface morphology was measured and the crack initiation Angle and location were determined for comparison with the simulation results. This folder is a collection of morphologies of different positions on the inner surface of the experimental shaft with a rotation frequency of 2×105 times. 2d is a plane photo, 3d is a stereoscopic photo, origin is a black and white photo, and 2d is for the convenience of observation.
