Characterization of wheel-rail contact
Assessing the main wheel-rail contact parameters for international type approval and check rolling stock behaviour in relation to the risk of instability.
- Measure wheel and rail profiles
- Establish wheel-rail contact parameters: Equivalent conicity, real conicity, radial steering index, etc.
- Gauge for spot measurement of wheel and rail profiles
- Calculation software for wheel-rail contact parameters
