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

Features

Wheel & rail contact test rig

Test rig electronics with real-time capabilities

Wear-free AC motor drive concept for bogie and rail wheels

High-precision rail wheels for a realistic representation of continuous track

Hydraulic load unit for controlled application of multi-axis dynamic loads (wheel vertical force, thrust + lateral force)

Environmental simulation (rain, low temperatures, snow)

Technical data

The maximum values listed here show the range of current systems, however, due to constant further development they do not necessarily specify the limits of what is possible today.
