| Abstract: | In this paper,a grinding experiment on a piston skirt profile coated with compound material in a high-power locomotive diesel engine is carried out under a rating condition.Precise three-dimensional coordinate instruments are also employed to get the three-dimensional coordinate value of the discrete points in the actual measuring piston skirt profile. Finally the datum of the piston skirt profile is simulated and modified based on the measuring result.A conclusion could be drewn,from which it is successful and effective to determine a piston skirt profile by this method. |
