Autonomous Prognostics and Health Management (APHM)
PHM Society European Conference, 2012The objective of this paper is to show how PHM con-cepts can be included in the design of an autonomous Un-manned Air Vehicle (UAV) and in doing so, provide effec-tive diagnostic/prognostic capabilities during system opera-tion. The authors propose a PHM Cycle that is divided into two parts, covering the design of the Autonomous PHM system and the ...

Prognostics and Health Management (PHM) System requirements and validation
2010 Prognostics and System Health Management Conference, 2010This paper based on four key abilities of the Prognostics and Health Management (PHM) System including the abilities of fault detection, fault isolation, fault prognosis and prognosis of the remaining life, analyzes and constructs a framework of the PHM quantitative requirements, and defines the quantitative assessment emphasis of the PHM abilities ...

Prognostics and Health Management
2012There is a need to acquire knowledge of LED’s life cycle loading conditions, geometry, and material properties to identify potential failure mechanisms and estimate its remaining useful life. The physics-of-failure (PoF) approach considers qualification as an integral part of design and development and involves identifying root causes of failure and ...

Air vehicle prognostics and health management
2000 IEEE Aerospace Conference. Proceedings (Cat. No.00TH8484), 2002Affordability in both acquisition and support is a key objective of the Joint Strike Fighter (JSF) Program. The concept of Autonomic Logistics, or the automation of previously labor-intensive, routine tasks, has been identified as the enabler of a streamlined support concept.

Stirling cryocooler prognostics and health management (PHM)
2009 IEEE AUTOTESTCON, 2009Tactical Stirling cryocoolers are life-limited components used in many IR sensing systems. Thousands are deployed in commercial and military systems. Using prognostics to predict impending failures will allow cryocooler replacement when it is convenient and cost-effective, rather than during system operation. This both reduces cost and improves mission

Prognostics and Health Management of Mechanical Systems
Advanced Materials Research, 2013Reliability is an important issue to consider for mechanical systems. The state of art is regular checkup and maintenance to ensure normal operations. This is not good enough for safety-critical systems like gearboxes in vehicles and helicopters because the risk of system failure still exists, let alone the manpower and monetary cost required ...
