Measurement campaign with a tram in the Netherlands

At the end of the year, we once again had the opportunity to accompany a tram from our customer Stadler Rail AG during its approval process in the Netherlands – the fourth one this year.

 

Approach:

As an accredited testing laboratory in accordance with EN ISO/IEC 17025, we support our customers in comprehensively demonstrating the safety, reliability and comfort of new vehicle models. These tests are an essential milestone on the road to approval and also provide valuable impetus for optimisations in later operation. The focus is on whether the new vehicles meet the requirements for driving behaviour, comfort and occupational safety. To this end, we record all relevant parameters in accordance with applicable standards and customer-specific specifications – the basis for a transparent and reliable assessment.

For the current campaign, the vehicle was equipped with over 60 sensors in the Netherlands and the measurements were carried out on the existing road network there.

As always, data is collected using our proprietary ACQUA® software solution. It enables seamless real-time recording of all sensor signals directly on board. Any anomalies are immediately visible and can be directly classified and documented – a decisive advantage for the safety and efficiency of the campaign.

The evaluation is done according to international standards and the specific requirements of our customer:

  • EN 14363 – Assessment of running behaviour

  • EN 12299 – Analysis of passenger comfort

  • ORE C 116 RP8 (Sperling's ride index / Wz-factor-method) – Comfort and running quality assessment

  • ISO 2631-1 – Effects of whole-body vibrations on humans

  • ISO 5394-1 - Effects of vibrations on the human hand-arm system

 

Result:

Our structured approach and precise data collection enable us to obtain reliable and meaningful results on driving dynamics, comfort and vibration loads. For our customers, this means:

  • Clear, comprehensible and traceable results that provide a solid basis for decision-making

  • Early identification of optimisation opportunities in the vehicle concept

  • Strengthening of internal quality assurance through standard-compliant analyses

This enables us to provide our customers with maximum safety, reliability and planning security – from development and approval to subsequent operation.
