Research and development

 

In the research and development area there are many measuring tasks which can be performed by means of laser sensors, and of which only a few are to be mentioned exemplary in the following.







 

Measuring of wheel position


The high scanning frequency of the OPTImess sensors (up to 50 kHz) provides the possibility to scan the wheel's outer side. By the defined positioning of the sensors at the sides of the railtracks, the recording of the wheel-sets' positions within the rails is possible at high speed. With this kind of in-line positioning of several sensors within the area of points, it is also possible to reach conclusions about the running behaviour of wheel-sets in points and to optimise guides inside of points.

 


Behaviour wheel / rail

 

By simultaneous measuring of rail and wheel positions the wheel-set's running behaviour can be recorded (sinus running). Due to the wide measuring distances, it is possible to install the sensors suitably protected below the carriages.

 

 

 

 

 

 

 

Other applications

 

Measuring of rail movements
Approach measurements during wagon connecting
Heeling measurements of wagon superstructures
Recording of the current-collector position

 

These examples of application have been listed to point out the diversity of the OPTImess sensors for measuring processes in railway practice. The variety of measuring ranges (4-800 mm), high scanning frequencies (up to 50 kHz), small size, and operating possibilities on nearly all kinds of surface, as well as insensibility with regard to impact stress, are properties which have turned laser sensors into an universal sensor for measurements in the area of wheel/rail. Many kinds of application are also transferable to measuring tasks in underground and local transport organisations.
