CETEST is qualified to carry out a range of stationary tests such as wheel unloading, roll coefficient and X-factor tests according to international standards, including EN 14363, UIC 528, and US CFR 49.
Stationary tests are required to evaluate the safety against derailment on rolling stock.
Having completed numerous projects worldwide, we have accumulated a good deal of experience in this area. We provide on-site test services thanks to our specially designed portable rigs prepared to be transported anywhere that reduce lead times and client costs. You do not need to move your vehicle, we bring our equipment to you, anywhere, anytime.
These test benches have been specially designed for the proper execution of the following tests:
- Wheel unloading
- Wheel equalisation test
- Roll Coefficient (also known as lean testing, sway or souplesse test)
- Bogie rotational resistance and X-factor determination
- Gauge verification
- Carbody torsional stiffness
- Centre of gravity verification (three axis)
- Vehicle weighting
The rigs can be adapted to any wheelbase and track gauge and then positioned according to the required configuration.
On-track running dynamics
CETEST has completed multiple dynamic performance tests according to EN 14363, EN 12299, UIC 518, US CFR49 all over the world. The aim of running behaviour tests is to assess the running characteristics of railway vehicles.
The assessment involves the statistical processing of several ride dynamic related parameters, which are obtained from signals recorded during test runs.
The following evaluation tests are performed in accordance with the above standards:
- Running safety
- Track loading
- Ride characteristics
CETEST performs both simplified method and normal method as described on standard EN 14363, thanks to our proprietary solution of instrumented wheelsets. We have completed a lot of different test campaigns across the globe and on many different types of vehicles.
CETEST also has experience in managing complete test campaigns, including organising the test runs, dealing with train operator, as well as with infrastructure manager.
Our instrumentation includes accelerometers, displacement sensors, strain gauges, gyroscopes and other special sensing systems such as instrumented wheelsets. We use them in conjunction with the latest control and acquisition equipment and post-processing tools.
Comfort performance test
CETEST is accredited to perform comfort evaluation tests according to standard EN 12299. CETEST assesses vehicle motion by measuring accelerations in the range that affects human perception of comfort. These are then processed to obtain the comfort index. Vehicle performance depends on the running conditions: speed, load, track maintenance state, track layout, and others.
