The wheel-rail contact plays a key role in the vehicle dynamics from the point of view of rolling safety, ride quality, track fatigue, safety
against derailment or wheel and rail wear. Instrumented wheelsets are designed to measure the wheel-rail contact forces. CETEST offers, as a product or test service, its own patented strategy for strain-gauge based measuring wheelset solution, specially designed to minimize the effects of different sources of uncertainty. The calibration process appears crucial to assess the accuracy of this measurement system. CETEST decided to develop its own roller test bench for instrumented wheelsets, which allows the independent application of turn, vertical and lateral loads in both wheels. CETEST instrumented wheelsets have been proven under special environmental conditions, such as ice, sand and extreme temperatures, as well as at high speeds. Tried and tested in all market segments (metros, locomotives, high speed trains, special maintenance vehicles, freight wagons, active tilting technologies, variable gauge, etc.) and across the entire globe. More than 70 wheelsets have been delivered in the last two years!
