| Abstract:One type of engine had the problem of big noise and serious piston wearing. Using laser knife 3D scan technology to detect the contour, thus obtained the contour data and diameters of the key locations. By roughness analysis, the wearing condition of the concerned areas was studied. The research results showed that the over-wearing was caused by deformation of the piston. Moreover, as laser knife 3D scan system has little requirements on application environment, and is one kind of non-contact measurement, it is easy for operation, has high accuracy and wide application range, and therefore could be used in further engineering application. |
