Analysis on Integrated Design of Military Aircraft PHM System

摘要:

军用飞机故障预测与健康管理（PHM）系统设计与工程应用存在设计标准缺失、复杂度高、准确率低等问题。通过对PHM 系统数据、结构、功能维度的设计需求分析，提出三维多相迭代设计准则；基于三维多相设计准则对PHM 系统设计流程进行梳理；提出基于软硬件协同加速的健康管理实时化、基于知识图谱的知识逻辑可视化、基于MBSE 的PHM 系统模型化的三化一体设计架构，并通过多领域模型联合仿真进行验证。结果表明：该设计架构实现了5.63 倍的加速计算效果与82.7% 的计算功耗缩减，提升了PHM 系统知识与设计需求 管理的可追溯性。

Abstract:

Aiming at the problems of lack of design standards, high complexity and low accuracy in the design and engineering application of prognostic and health management (PHM) system for military aircraft, the design requirements of data, structure and function dimensions of PHM system are analyzed. Based on the study of the relations and characteristics of the three dimensions, the three-dimensional multiphase iterative design criteria is proposed. A three-in-one design architecture of real-time health management based on embedded system, knowledge logic visualization based on knowledge graph, and PHM system modeling based on MBSE is proposed. The PHM system design process is constructed by analyzing the PHM system design strategy, which provides a method for the engineering application of military aircraft PHM system.
