Abstract

The invention discloses a virtual maintenance based maintainability analysis method for an aircraft part. Firstly, a maintenance attribute value of the to-be-analyzed aircraft part is quantitatively determined, wherein the maintenance attribute value comprises human factor engineering, reachability, simplified design, modularization, standardization and interchangeability, and testability; secondly, a natural language is quantitatively processed; thirdly, according to the obtained attribute value, performing weighted calculation on a comprehensive maintainability attribute value of the to-be-analyzed aircraft part; and finally, according to the comprehensive maintainability attribute value, calculating degree of membership, and obtaining comprehensive maintainability evaluation and partial evaluation of the to-be-analyzed aircraft part. According to the method, on the basis of determining maintainability influence attributes, each maintainability influence attribute is analyzed and inspected, an evaluation method for maintainability quantitative requirements is proposed, and parallel design-oriented maintainability qualitative analysis and evaluation are realized, so that design defects can be discovered in time and the improvement on maintainability design is facilitated.

Description

technical field [0001] The invention relates to the field of virtual maintenance, in particular to the maintenance based on virtual reality technology, which simulates the maintenance process in a virtual environment, and analyzes the maintainability of the aircraft according to the simulation data. Background technique [0002] Traditional maintainability analysis techniques and methods are mainly based on expert experience, similar aircraft maintenance experience, historical data, etc., and a considerable number of work items need to rely on physical prototypes, and even tests or demonstrations can only be carried out after the aircraft is successfully developed. [0003] However, if the maintainability is analyzed and judged based on expert experience and historical data, rich experience is needed to give more accurate analysis results. If the analysis is carried out on the basis of a physical prototype, the development cycle will be extended and the research and developm...
