Vibration tests
We test the mechanical resistance of objects, equipment, and devices to vibrations and shocks. We can combine vibration tests with environmental testing.
- 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 traffic operation on roads and rail.
- Laboratory strain measurements of uniaxial and multiaxial stress.
- Seismic qualification for nuclear facilities (items, devices, and equipment).
The testing laboratory is equipped with two single-axis electrodynamic vibration tables that can be combined with a climate chamber.
The testing laboratory is also equipped with a hydraulic system for multi-axis loading, which allows vibration tests to be performed on specimens weighing up to 10 tons. Among other things, the hydraulic system makes it possible to simulate road profiles and generate vibrations in all degrees of freedom.
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 apply any specified signal within the above-mentioned range at any specified point on the equipment.
- FEM analyses combined with verification.
- Predefined road and rail profiles for vibration testing, with the option to significantly accelerate life-cycle testing based on real acceleration.
- Vibration testing in accordance with ASTM (transporting applications).
- We perform accredited tests in accordance with the following standards:
