SUMMARY:Qld Chapter Event: Using supercomputing to assess the influence of wheel diameter differences on rail damage
DESCRIPTION:Overview\nWheel diameter differences (WDD) on railway vehicles impact the dynamic behaviour\, the traction system performance and rail damage. It is well known that the various types of algorithms that govern locomotive adhesion control systems may compensate for the presence of WDD. However\, detailed studies on the influence of adhesion control algorithms on rail wear and rolling contact fatigue (RCF)\, under the presence of WDD\, have not been published. \nFurthermore\, several standards establish WDD limits for wheelsets\, bogies and vehicles which\, in turn\, determine the planning of wheelset maintenance activities. There is no information in the public domain on how such limits were set and their impact on the dynamic processes at the wheel-rail interface. Thus\, a numerical program comprising thousands of multibody dynamics simulations should be conducted to study the influence of WDD on vehicle performance\, considering several combinations of operational parameters\, in-train forces and the responses of a locomotive traction mechatronics system. The practical methodology including the example of results from such a numerical program and the analysis of the impact of WDD on rail damage and vehicle performance will be presented. The pathway for the development of digital twins for such tasks will be also presented and discussed. \nLearning outcomes\n\nDevelopment and use of digital twins for railway applications.\nWheel diameter difference standards and its influence on rail wear and rolling contact fatigue.\nModern techniques for using physics-based digital twins and supercomputers for railway applications.\n\nEvent program\nOnline: \n\n12.00pm: Webinar commences\n12.55pm: Webinar concludes\n\nIn-person: \n\n11.45am: Registration and light refreshments\n12.00pm: Welcome\n12.05pm: Speaker presentation\n12.45pm: Q&A\n1.00pm: Networking\n1.30pm: Event concludes\nTicket inclusions: Light refreshments\, soft drinks\n\nAbout the speaker\nEsteban Bernal\, Senior Research Officer\, Centre for Railway Engineering\, CQUniversity \nEsteban Bernal is a Senior Research Officer at the Centre for railway Engineering\, Central Queensland University\, Australia.
