Embodiment Construction

[0026] The invention proposes a method for constructing a three-dimensional virtual maintenance simulation model based on an operating unit based on the idea of ​​low coupling and high aggregation. The maintenance task operation is decomposed into the minimum, inseparable disassembly and assembly operation unit, and the simulation motion model is established for it, that is, the operation unit model. As the basic motion model of maintenance simulation, the operation unit model only contains the motion information of the basic maintenance operation, and is not directly related to the 3D model. There is no correlation between the operation unit models, and they all exist independently. Then define the association relationship in the digitalized maintenance process information file of the visual definition, edit and export structure, combine the modularized operation units according to the maintenance task process in the way of "finding out the picture", integrate the correspondin...

Abstract

The invention provides a three-dimensional virtual maintenance simulation model construction method based on an operation unit. The creation of a maintenance flow simulation model, the construction ofan operation unit model and the construction of a maintenance task simulation model are completed in sequence. According to the invention, the maintenance task operation is decomposed into the minimization of the non-redivisible disassembly and assembly units, namely the operation units, only the motion information of the basic maintenance operation is contained, the operation units are managed in a discrete manner, and the operation units have no association relationship and exist independently. The operation units are made to correspond to the digital prototype model and the maintenance task flow nodes by defining the incidence relation, the operation units can be combined according to the maintenance task flow, when the same node exists in the maintenance task flow, the operation unitscan be directly reused, and maintenance simulation models with different layer granularities are generated. Thus, low-coupling and high-aggregation data association is used for achieving flexible andrapid construction of the three-dimensional virtual maintenance simulation, the workload is reduced, and the three-dimensional virtual maintenance simulation construction efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of aircraft maintenance, and in particular relates to a method for constructing a three-dimensional virtual maintenance simulation model based on an operating unit. Background technique [0002] With the increase in the complexity and integration of new aircraft systems, the aircraft maintenance process is becoming more and more complex, and the requirements for the knowledge and skill level of maintenance personnel are also increasing. Maintenance personnel need to memorize a large amount of data, operating procedures and steps. At present, in the computer environment, the traditional 3D virtual maintenance simulation adopts the method of generating animation scripts according to the maintenance operation process, combined with 3D models to render 3D animation. This method is more intuitive and economical, but if the model or maintenance operation process is changed, it needs to be completely recreated. The...
