KOMAG Laboratory of Applied Tests extended its activity by vibration tests/exposures. Our testing equipment enables vibration tests in 3 perpendicular axes of objects weighing up to 900 kg. Exposures may take place in the following scope of parameters:

• Force: up to 70 kN (sinus, random),
• Force: up to 140 kN (shock),
• Frequency: (5-2000) Hz,
• Max acceleration: 900 m/s²,
• ax displacement: 75 mm p-p

  

The tests can be applied in scientific, experimental and engineering research work and for certification of new products or technologies. It is possible to test products according to standardized test procedures or the client's own testing methodologies. Examples of standardized testing methodologies are as follows:

• PN-EN 60068-2-27
• PN-EN 60068-2-64
• PN-EN 50125-3:2003 p.4.13
• PN-EN 61373
• PN-EN 60068-2-6
• MIL-STD 810F, Metoda 514.5, procedura I
• Norma NO-06-A107
• DO-160
• ETSI EN 300 019-X-X
• Regulamin nr 100 EKG ONZ
• UN 38.3

The tests can be used in the automotive, mechanical, aviation, railway, lighting, electric, space, transport, electromobility, military, medical, electronic, telecommunications, etc. industries. A wide range of applications enables testing the end products as well as machine and device subassemblies.

To diagnose damage or to gain knowledge about the tested product, high-speed video recording is also possible during the vibration tests, which will allow for a detailed analysis of the object's behavior during exposure to vibrations. A high-speed camera with the following parameters is used:

• Bandwidth 3 Gpx/s,
• Maximum resolution 1920 x 1080 pixels,
• Speed in full resolution 1 480 fps,
• Maximum speed is 94 695 fps (at a resolution of 640 x 8 pixels).

In addition, the following is tested:

•  machines and equipment
• in working environment

according to the following standards:

• PN-N-01352,
• PN-N-01357,
• PN-N-01358,
• PN-EN ISO 5349-1, PN-EN ISO 5349-2,
• PN-EN ISO 28927-10,
• PN-EN 14253,
• PN-ISO 14695,
• PN-EN 60745-1, PN-EN 60745-2-3,
• vibration measurements by spectral and weighted methods in the 1/1; 1/3; 1/12; 1/24; 1/24 oct. bands,
• FFT analysis,
• time curves.
