SCOPE This SAE Aerospace Recommended Practice (ARP) examines a comprehensive construct of an Integrated Ve

17、hicle Health Management (IVHM) capability. This document provides a top-level view of the concepts, technology, and implementation practices associated with IVHM. This keystone document of the SAE HM-1 Committee is not intended as a legal document and does not provide detailed implementation steps,

18、but does address general implementation concerns and potential benefits. Figure 1 provides a document flow map of the documents currently in work or planned by the Committee. The documents shown below will provide the recommended practices for IVHM implementation. This document map reflects the curr

19、ent SAE IVHM document configuration as of the date of publication. Future documents that are released will be included in the flow map in future updates of this document. Figure 1 - HM-1 document flow map An indication of the scope of IVHM is diagrammed in Figure 2. When an organization decides to i

20、mplement an IVHM capability as part of their product sustainment strategy, the decision must consider the business objectives and user perspectives driving the decision, the system architecture and design to support the impetus, the Technology Readiness Level (TRL) or maturity of the technologies in

21、volved, the unique aspects of the operational environment and infrastructure, and the tools required to support the IVHM life cycle. This document discusses significant aspects and considerations of the interrelated IVHM elements listed in this diagram. ARP6803 SAE INTERNATIONAL ARP6803 Page 4 of 51

22、 Figure 2 - IVHM taxonomy 1.1 Purpose Aerospace asset owners, operators, and maintainers are under increasing pressure to reduce maintenance and operations costs, to maximize system and component useful life, to reduce maintenance down time, and to increase availability, while not compromising safet

23、y. At the same time, maintenance personnel need to know what component or system requires maintenance and what maintenance actions must be taken. Operations personnel need to know when an aircraft can be operated reliably and when it can no longer be operated without incurring an unacceptable risk o

24、f failure. Additionally, fleet management personnel need to know when an aircraft should be scheduled for maintenance, what components are required in advance of a scheduled maintenance event to reduce logistics-related maintenance delays, and what impact these maintenance events will have on the av

25、ailability of resources with respect to the overall fleet. All this needs to be achieved with, at a minimum, no adverse impact on existing safety levels. As a result, the objective for implementing an IVHM capability is to provide unambiguous actionable information on the health of aircraft systems

26、and components that can be used to reduce operating and maintenance costs while taking into consideration the life cycle cost and satisfaction of safety requirements. 2.

The RCM report also acknowledged that OCM, along with redesign and/or redundancies (for critical systems), were the only practica

38、l and effective approaches to deal with most failures. IVHM was subsequently conceived by the National Aeronautics and Space Administration (NASA) as a means of integrating a disparate approach to Vehicle Health Management, with certain stakeholders applying predictive maintenance to their part of t

39、he space vehicle (engine, airframe, etc.) This vehicle centric view was fine when there was one or a very limited set of vehicles in a fleet. This is not the case in most other applications. ,QWHJUDWHG9HKLFOH+HDOWK0DQDJHPHQW Perspectives RQDQ(PHUJLQJ)LHOG provides a thorough background of the evolut

40、ion of IVHM, which aimed to provide a holistic platform centric view of the vehicle. This platform centric perspective placed great emphasis on Systems Engineering processes.

Maintenance policies and procedures need to be sufficiently flexible to keep up

42、 with this diverse portfolio. The future of IVHM will lead to greater automation, which implies diluting to some degree the human expertise currently involved in maintaining vehicles, and, in some cases, manufacturing vehicles that can self-maintain and become damage tolerant. As unmanned platforms

43、become more prevalent, IVHM will be a valuable tool to capture expert diagnostic and prognostic knowledge through the use of artificial intelligence, machine learning, and statistical techniques.
