[Abstract]:With the development of aeronautical technology, the degree of integration of aircraft systems has been improved, and the number of avionics components has become more and more complex, which has become an important part of aircraft. Maintenance of avionics components is an important part of maintenance work. Therefore, it is of great significance to establish an avionics module simulation model for maintenance training. In the aircraft maintenance simulation, aiming at the problem that the simulation model of avionics component is not unified and reusability is poor, through analyzing the process logic of the maintenance task of avionics component, this paper aims to establish a standardized simulation model of avionics component. To suit the needs of multiple training models. The main contents of this paper are as follows: 1) the overall framework of the simulation model of maintenance mission driven multi-training avionics module is constructed. Firstly, on the basis of the induction, summary and classification of avionics components, the semantic network representation is used to describe the generic relationships of avionics components. Secondly, the maintenance tasks of avionics components are analyzed and classified according to their working contents, and the five maintenance behaviors which need to be satisfied in the simulation of avionics components are summarized. Thirdly, according to the actual requirements of maintenance training for airlines and civil aviation colleges, two training modes are analyzed and summarized. Furthermore, the overall design idea and framework of avionics component simulation model based on maintenance task driven under these two training modes are presented. 2) A standardized modeling method based on SCM (Simulation Component Model) is proposed to establish the functional model of avionics component. Firstly, the functional model framework of avionics components is defined by SCM specification. Then, according to the characteristics and functions of avionics components in the maintenance simulation process, four kinds of input signals are summarized and defined, and the functional operation between model input signals, control signals and output signals is also specified. To meet the test class and troubleshooting class maintenance task requirements. Thirdly, the maintenance task processing module in the model is defined, which is used to deal with the interaction between the simulation environment and the trainers about the task information. 3) the behavior expression of the assembly and disassembly of avionics components is studied to meet the needs of the disassembly and assembly maintenance tasks. Firstly, the process and method of constructing the geometric model of avionics components are analyzed. Then, a formal behavior model is defined, and collision constraints, disassembly logic constraints and disassembly path planning are studied, and the changing process of disassembly and assembly state is described by finite state machine (FSM). Finally, the effectiveness of the model is verified by taking the flight stability enhancement computer simulation maintenance process as an example. The establishment process of the geometric model, the behavior model and the functional model of the flight stability enhancement computer are described, and the model expression is realized on the self-made aircraft maintenance trainer, which meets the requirements of the multi-training mode and the maintenance task. It shows that the model is practical and feasible.
