Case Study: Siemens Mobility achieves safer, more accurate bogie testing with Qlar Bogie Test Bench

Siemens Mobility boosts bogie testing accuracy to ±0.1% with Qlar

Siemens Mobility, a major rail vehicle manufacturer, required a highly accurate and reliable quality assurance system for testing the thousands of bogies produced annually at its Graz plant. The challenge was to ensure every bogie met strict safety standards by precisely measuring wheel contact forces and geometric dimensions before delivery. To meet this need, they turned to vendor Qlar and its Qlar Bogie Test Bench.

The solution implemented by Qlar was a test bench featuring a patented, fully automatic bogie positioning system and an automated test process. This system provides extremely precise measurements, with average deviations of just ±0.1% for force and less than 0.2 mm for geometry. The results for Siemens Mobility include high process reliability, nearly 98% availability, and enhanced ergonomics for operators. The long-term partnership with Qlar has provided the flexibility and accuracy needed to ensure greater safety in rail transport worldwide.
