Abstract: In the paper, a geometric error online measurement system for marine diesel cylinder liner has been designed. The impact of the position error and the installation and measurement errors of sensors on the accuracy of each measurement point coordinate was analyzed, and a mathematical model for measurement error was thus discussed. Accordingly, a mathematical model for evaluating the straightness, roundness, and cylindricity errors of diesel cylinder liners was established based on nonlinear programming. The model is more accurate compared with the existing measurement method. A prototype measurement system was constructed as well, and the experimental data show it is simple, precise and efficient.
Keywords: marine diesel cylinder liner;geometric error;online measurement;nonlinear programming
