RISA Graph-Based Fault Identification and Propagation Framework for Functional Design of Complex Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the functional-failure identification and propagation (FFIP) framework is introduced as a novel approach for evaluating and assessing functional-failure risk of physical systems ...
Analysis of Triaxial Vibration Data for Health Monitoring of Helicopter Gearboxes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Research on the nature of the vibration data collected from helicopter transmissions during flight experiments has led to several crucial observations believed to be responsible for the high ...
Toward Intelligent Fault Detection in Turbine Blades: Variational Vibration Models of Damaged Pinned-Pinned Beams
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Inaccuracies in the modeling assumptions about the distributional characteristics of the monitored signatures have been shown to cause frequent false positives in vehicle monitoring systems for ...
ASME Journal of Mechanical Design Special Issue 2012: Design under Uncertainty
Publisher: The American Society of Mechanical Engineers (ASME)
