Integrated Vehicle Health Management (IVHM) for Power Electronics
Dr. Suresh PERINPANAYAGAM, Cranfield University, Integrated Vehicle Health Management (IVHM) Centre
Integrated Vehicle Health Management (IVHM) is the transformation of system data on a complex vehicle or system (such as a luxury car or a commercial airplane) into information to support operational decisions and optimise maintenance. IVHM is a capability, comprising a number of technologies that can be used across a number of sectors for business benefit. IVHM is becoming increasingly important as OEMs (Original Equipment Manufacturers) move from the traditional sale of a product, in which future income is dependent on spare part revenue, to selling a service in which steady monthly income can be derived in return for the effective maintenance of the asset. IVHM enables this transformation. The IVHM Centre delivers generic IVHM solutions including capability to sense, detect, diagnose, and predict imminent degradations or failures in vehicles, thereby allowing the evaluation of the reliability of the systems under real application environments. This presentation will focus on investigating the capability of health monitoring techniques to detect degradation of electronic and power electronics in an integrated avionic system.
About the lecturer
Dr Suresh Perinpanayagam leads the ePHM Group, part of the Boeing Integrated Vehicle Health Management Research Centre set up by The Boeing Company. Suresh has rapidly established a research group, managing 14 researchers (2 research fellows, 6 full-time PhDs, 2 MSc by research and 4 MSc by taught course students) and has obtained grants amounting to £1.4M in total from industrial, EPSRC, TSB and EU-FP7 projects. Suresh obtained his Master in Engineering and PhD in Engineering at Imperial College, London. Suresh has spent considerable time in industry working on various industrial R&D projects. Suresh’s vision is to create every electronic system with its own brain to be self-aware of its own health state and to work effectively with other systems to complete a function even if it is not in an optimal state. To realise this, the group develops tools to detect the inception of failures in electronic components and track them to system failures. They also need to correlate the fundamental physics-of-failure work currently done at material science level (for example, solder joint and wire bond failure) to the electronic system data acquired for system health management from data-centric aircrafts, such as Boeing 787. These intelligent electronic systems will inform and reconfigure its health state at different stages of its life. These new systems will redefine the current Built-In Test (BIT) technology in electronic systems with more user-friendly, reduced no-fault-found rate, reduced repair, reduced cost, predictable failures and greater availability for industry. The ePHM group has links with many of the UK’s high value added electronic system manufacturers, including AEC, Thales, Selex, BAE Systems, Meggitt, GE, Honeywell, Cassidian, General Dynamics, UTC, Raytheon and Visteon Corporation. The group uses this forum to connect fundamental research issues in material, design, manufacturing process, testability, system issues and through-life management of these electronic systems.
THE guest lectures WILL TAKE PLACE in Pon 111 in the auditorium and all are welcome.
