Mechanical testing
Our mechanical test capabilities cover vibration and physical shock conditions. Mechanical testing is a systematic and repeatable way of identifying mechanical, electrical and functional weak points of a design. Hence it represents an intelligent approach to verifying product design and choice of materials. Testing already at the prototype stage can help you avoid technical errors and quality deficiencies before they become costly.
Our air-cooled electrodynamic shaker is suitable for vibration testing of small to medium sized payloads, such as individual electronic components, assemblies, optoelectronics, automative and industrial components. Useable weight range for the unit under test is 0 to about 160 kg.
We can help you with different types of tests such as accelerated lite test, sinus vibration, shock and srs (Shock response spectrum), random vibration and resonance test. Our shaker can also be integrated with our environmental test equipment, allowing for combined mechanical, thermal and humidity testing. Both temperature and climate influence the vibration behaviour of materials. For this reason, constant as well as cyclically changing temperatures and climates are important during vibration testing. Unambiguous ambient conditions during testing with sine excitations, noise, sine on noise or even shock testing lead to solid results considerably faster.
Temperature and climatic test
The climate chamber handles temperatures from -70 to 180 °c with humidity values from 10 % to 95 % rH. The lifetime effects of product exposure to such climate-related conditions as extreme temperatures or humidity changes can be modelled using our climate chambers that allows for accelerated studies.
Our chamber is equipped with sophisticated control equipment that can be programmed to simulate complex exposure cycles. Needless to say, testing at constant temperatures and humidity levels is also available. This flexibility permits testing in accordance with a wide variety of standards. Separate logging stations record the actual conditions inside the chambers. Printouts of raw data can be obtained.
Examples of the most common climate standards:
- IEC 60068-2-1 Cold
- IEC 60068-2-2 Dry heat
- IEC 60068-2-14 Change of temperature
- IEC 60068-2-30 Damp heat cyclic
- IEC 60068-2-38 Composite temperature, humidity cyclic test
- IEC 60068-2-78 Damp heat, steady state
Our environmental test equipment can also be integrated with our shaker, allowing for combined mechanical, thermal and humidity testing.
