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，对材料为45钢的废旧电机轴表面形貌进行测量，其测量部位为电机轴轴承位的配合面边缘，从而对边缘应力集中引起的塑性变形造成表面轮廓的变化有一个量上的认识，这表明接触边缘的塑性变形是一个重要的损伤形式。

The equipment used in this article is the NewView9000 3D surface optical profilometer produced by ZYGO Company with a magnification of 10x. The surface topography of the waste motor shaft made of 45 steel is measured. The measuring part is the mating surface edge of the bearing position of the motor shaft. The results show that the plastic deformation of the contact edge is an important damage form.
