Research On Simulation Method Of Maintenance Measurement Process Based On Maintenance Tasks

At present, aviation maintenance technology becomes more and more complex, therefore,maintenance costs, maintenance technology as well as maintenance staff skills and knowledge have become increasingly demanding. In today's aircraft maintenance training equipment,there is almost no simulation of the measurement process, and it puts forward three kinds of simulation methods of aircraft system measuring process specified in CCAR-147-04, to improve the aircraft repair training equipment and technology level, improve training efficiency, save the training time and cost, improve staff repair ability.a. In the Trouble Shooting Manual, according to the existence of the measurement process, the maintenance task is divided into two categories. And the purpose of these measurements is to confirm the point of failure. Moreover, according to different classification criteria for the classification of the measurement process.Use the methods of the modular to process the whole measuring process of aviation maintenance, and give the definition of the whole measuring process.b. According to the measurement point has not unique, the complex logical relationships between the measurement job,etc. Select one appropriate method to establish a process simulation model. Three different simulation processes based on previous research and application ared designed, and combined with the particularity of each class of the measurement process. They are Petri net, IDEF3 and DSM.c. Using three different methods to establish simulation models for the measurement process with different features. Petri net is used in the rudder damping measurement process,IDEF3 is used in the fluid leakage measurement process and design structure matrix is used in the resistance measurement process.
