Wheel & rail contact test rig

A perfect interplay between the wheel and the rail is required when heavy vehicles travel on tracks on a daily basis. RENK´s wheel & rail contact test systems reproduce this interaction perfectly in the lab setting.

In addition, a wheel-rail system test bench provides a wide range of testing options for all assemblies of the wheelset. All loads and environmental influences are realistically mapped, such as:

  • Developing new materials and heat treatment methods for wheelsets
  • Analyzing curve squeal and the influence of wheel absorbers
  • Developing future braking systems
  • Developing and calibrating diagnostic systems
  • Analyzing lubricant distribution and damage pattern
  • Optimizing wheelset axles
  • Monitoring running dynamic behavior
