Mechanical testing

The vibrating pot is a test method used to excite a vibrating structure. Vibration tests are essential because they make it possible to understand the dynamic behaviour of equipment, to predict how they might fail and to improve reliability. To cite an example, one can simulate the transport, preparation and launch, or even the orbital life of an instrument on board a satellite. Several principles of usage are possible depending on the type of test to be performed (random, sine, shock, resonance research and monitoring).
   

• Max sine force: 40 kN
• Max random force: 40 kN
• Max force in conventional shocks: 80 kN at 30 Hz
• Max peak-to-peak displacement: 51 mm
• Max speed: 1.8 m / s
• Max sine acceleration: 100 g
• Max random acceleration: 60 g
• Useful frequency from 5 Hz to 2500 Hz

The vibrating pot is an ETS system equipped with a magnesium expansion head and two interchangeable tables of 300 x 300mm and 600 x 600mm (vertical tests). This system is installed in a clean room under 6m² of ISO5 laminar flow. The target level of cleanliness in the room is ISO6 / ISO7 thanks to a recycling operation.
The acquisition front-end can accommodate 18 measurement channels. We have 18 ICP accelerometric sensors (mixed: 3 axes, single axes, drop of water, etc).
