ICRI Project: Profile Scoring
Profile Scoring
Profile Scoring
Lead: Ankur Ashtekar, Sentient Science
Description:Developing a methodology to evaluate the performance/suitability of a rail profile for use under a specific set of conditions through profile scoring. This tool would provide scoring that would help determine what is the best profile, from available and new profile templates, given the current state based on performance with respect to wear, RCF, lateral and curving forces, stability and ride quality, noise and corrugation resistance, grinding, and frictional energy. Cost and economic implications would also be considered. The score would be used to rate if the current state is “good enough”, and compare this actual to an expected optimal.
Several parameter working groups have been identified, as listed in Table below. Each group will be responsible for developing a scoring method which would feed into the overall profile scoring.
| Group | Lead | Status |
| RCF/Wear | Kevin Oldknow | Team defined |
| Lateral Stability and Curving Forces/Dynamics | Peter Klauser (Vehicle Dynamics) | TBD |
| Corrugations Resistance/Noise | Mark Reimer (ARM) | TBD |
| Grinding | Charles Rudeen (LORAM) | TBD |
| Frictional Energy | Rob Caldwell (NRC) | TBD |
