WA/VIC/TAS Joint Chapter Event: Adhesion condition estimation between wheels and rails
Join the RTSA WA and VIC/TAS Chapters for this webinar on Adhesion condition estimation between wheels and rails online at 3:00-4:00pm AEDT on Thursday 8th December.
Overview
This presentation will discuss how the adhesion condition between wheel and rail can be estimated and how the braking performance of a rail vehicle can be improved utilising the obtained adhesion information. The methodologies used for adhesion estimation are based on specially designed algorithm development, numerical modelling, and scaled laboratory experiment (Hardware-in-loop) techniques were used to analyse the braking performance. The presentation will also discuss the basics of wheel-rail contact mechanics, rail braking control system, friction, and adhesion process at wheel-rail interface.
An ideal braking system not only ensures safety and ride comfort but also attracts significant cost-benefits through optimum on-time operation and reduction in wheel-rail damage processes. For such a braking system, the adhesion condition information between the wheel and rail at contact interfaces during rail vehicle operation is essential. The adhesion estimation for the braking system is a complex task because it is influenced by design, operational and environmental factors. The presentation is extracted from the presenter’s RTSA award winning PhD research work.
