Structures and Subassemblies

CETEST can carry out railway vehicle body structural testing according to EN 12663 at its test laboratory.

Thanks to our broad experience in this field we employ our test benches, either here at CETEST or using our portable test rigs on-site at your facilities, to provide a complete car body structural verification service.

We design, manage and perform structural testing according to EN, APTA, PRIIA, ASME, GM RT and other international standards. Our versatile car body frame structural test rigs are designed to apply service and exceptional loads, including longitudinal (compression and traction), vertical and lateral loads, jacking and lifting loads, as well as bogie body loads.

Our test laboratory is accredited for bogie and bolster fatigue testing according to EN 13749, UIC 515-4 and UIC 615-4. These tests are also mandatory to obtain component TSI homologation. The aim of these tests is to simulate operational life in a short period of time.

We have several state-of-the-art test rigs, which can be run simultaneously, specially designed to test bogies and bolsters. Our service includes non-destructive testing (magnetic particles inspection) at different test stages to detect crack formation or evaluate crack propagation.

CETEST boasts state-of-the-art equipment and measurement instrumentation; displacement sensors, load cells, control systems and up-to-date data acquisition software ensure our clients receive the best possible service.

We test couplers according to EN16019 or any specific standard required by the client. Tests are performed to obtain design validation and homologation and to characterise the full system.

At CETEST we have the necessary expertise and equipment required to test a broad range of components mounted on a rail vehicle. Functional and fatigue tests are designed according to client specifications.

Some examples of tests carried out in our facilities include:

  • Crash characterisation of energy absorption devices
  • Functional and fatigue tests on dampers
  • Functional and fatigue tests on roll bars
  • Primary and secondary suspension characterisation
  • Functional and endurance tests on traction rod and spherical joints
  • Fatigue tests on bogie frame supports
