![]() This enticing value proposition, along with a larger industry trend on the topics of Industry 4.0 and Smart Factory are sparking an increasing level of interest in PHM related technologies for manufacturing applications. Session Chair: David Siegel (Predictronics)ĭescription: Higher throughput, better product quality, and higher equipment availability, are the potential benefits that a well-designed prognostic and health management (PHM) systems can provide for manufacturing equipment and manufacturing processes. Panel Session Details Smart Manufacturing PHM NIST – National Institute of Standards and Technology.Leveraging Data Analytics for Digital Strategies in Commercial Aviation PHM for Corrosion Assessment and Remediation PHM for Corrosion Assessment and Remediation.Leveraging Data Analytics for Digital Strategies in Commercial Aviation.We believe balancing the conference time in this fashion provides participants a much more engaging experience and increased opportunity to gain unique knowledge. These sessions add an enriching dimension to the conference experience and a welcome networking alternative to traditional paper presentations, which dominate some conferences. These 90 minute panel sessions will consist of presentations and open discussion by 4-6 panelists directly engaging with the conference audience on the 12 different topics listed below.

By monitoring this frequency shift in real-time, catastrophic and costly failures can be avoided. We show evidence that a fundamental downhole frequency mode drops 30% during drilling operations as a crack propagates in the tool. In this work we demonstrate that downhole vibration measurements can be used for prognostic health monitoring and to track the structural integrity of the tools. Typical failures include cracks in the weaker spots of the downhole tools. Consequently, the stress on downhole tools has increased and fatigue failures are becoming more common. This improvement comes as a result of the greater capabilities of land rigs which are now able to push larger amounts of energy into the drilling system. In recent years there has been a substantial increase in the rate-of-penetration in drilling operations with the aim of reducing costs and reaching the reservoir in shorter times. ![]()
