Vibration tests

We test the mechanical resistance of items, equipment, and devices against the effects of vibration and impact. Vibration tests can be combined with climatic tests.

  • Electrodynamic vibration and impact equipment, including a sliding desk.
  • Multiaxial hydraulic systems.
  • Lifespan testing of highly stressed parts for rail, air, and road transportation.
  • Our own predefined profiles simulate real operation on roads and rail.
  • Laboratory strain measurements of uniaxial and multiaxial stress.
  • Seismic resistance tests (items, devices, and equipment).

The test lab is equipped with two single-axial electrodynamic vibration and shock desks, which can be combined with a climatic chamber.

The test lab is also equipped with a hydraulic system for multiaxial stress in vibration tests with a total mass up to 10 tonnes. The hydraulic system permits, for example, a road profile to be replicated and degrees of vibration generated freely.

Benefits:

  • Combining the equipment allows mechanical and climatic tests to be conducted simultaneously (a climatic chamber can be positioned over a vibration desk as necessary).
  • The ability to tune into any specified signal in the range defined above at any specified place on the equipment.
  • FEM analyses combined with verification.
  • Predefined road and rail profiles for vibration testing, with the option to significantly accelerate lifespan tests based on real acceleration.
  • Vibration testing in accordance with ASTM (transporting applications).
  • Our accredited tests are conducted under the following standards:
