Session 6: rail
grinding applications
|
|
1100-1130
|
Rail grinding:
· What is to be achieved?
- establishment /
maintenance of transverse profile
- removal of
"long" and "short" wavelength corrugation
- "acoustic
grinding"
- metal removal /
controlled wear
· How is it achieved in practice?
- grinding
"patterns" and their use
- effects of speed,
grinding pressure, power
· grinding motors and grinding power
· typical performance, productivity and
requirements
· "quality control"
|
Stuart Grassie (SGES,
Germany / UK)

Summary of Course
· What are the problems?
· Why do they arise?
· influence of vehicles:
- what is possible, how
can improved behaviour be encouraged, can "good" vehicles fix all
our problems?
· the wheel / rail interface, including the
influence of friction on vehicle curving
· track geometry: its influence on vehicle /
track interaction
· requirements of track
· recommendations, necessary compromises,
further work and "open questions"
