Abstract

Some balancing on engines, especially on engine CFM56 – 3 will make the difficult work for employee to do that method quick and correctly because balancing method on engines still done by manually if engines mounting on wing and engine shop (base) to do this maintenance is too far. Difficulty that has been found in working area encourage writer to conducting the research about make the automatic Three Shot Plot balancing based on matlab. Three Shot Plot Procedure is the manual simple method provided by engine manufacturing, expected by conducting this method can help the engine reduce the vibrating problem. In conducting this research, data has been collected on the different engines for this manual method, to provide a statistical comparison by value and taking a statistical decision on program calculation. Tested value is the output from designed program toward the manual method. Statistic test that has been used is Mann – Whitney test, this method classfied in non-parametric statistical test, this statistic test used for the small data and unnormal distributed. The program also tested the work time comparison on both method. The designed program then reviewed from working area condition in the real time, how useful this program to help balancing on this engine. The result of Mann – Whitney Statistical test and taking the decision on the disigned matlab program,the outputs has no difference toward the manual method. Based on the average of work time,matlab program can save a lot of time than the manual method. Based on working area factors, matlab program only able to eliminate that working area factors.
