摘　　要：往复冲击条件下,由磨损引起的接触表面磨痕的三维形貌的改变对接触润滑效应的研究具有非常重要的影响。在传统傅里叶变换轮廓术(Fourier transform profilometry,FTP)测量系统中引入正弦光强产生装置以及图像实时采集处理系统,利用单幅条纹图像,快速、准确地重构出磨痕表面三维形貌。利用该测量系统对施加PB2400型润滑油方式下快速冲击一万次后的磨痕形貌进行了测量,利用FTP对采集的条纹图进行处理,获得该磨痕的三维形貌。将测量结果与粗糙度轮廓测量仪所得结果进行对比分析,验证该方法的可行性和有效性。将该测量方法与高速摄像机相结合,可以实现连续冲击过程中磨痕的瞬时三维形貌测量,为进一步研究接触润滑效应提出一种新的试验依据和方法。Three-dimensional topography of surface abrasion under metal reciprocating motion has important influence to lubricant effect in point contact.The primary objective of this study is to demonstrate the feasibility of measuring 3D topography of surface abrasion.A new method to produce sinusoidal light system and real-time image acquisition and processing system are introduced into Fourier transform profilometry（FTP）,one fringe image is used to obtained 3D topography of surface abrasion.A surface abrasion under ten thousand times is used to demonstrate the validity of the method and the experiment results are compared with those obtained from surface profile.Contact with a high-speed CCD camera,the method can retrieve instantaneous contour from a continuous deformation object,and provide a new examination proof for further development of lubricant effect.
