They performed comprehensive vibration tests using a 96-channel m+p VibControl system and a 90 kN shaker.
Load tests performed on BASF’s shaker facility demonstrated the resin’s ability to satisfy extremely demanding specifications such as resistance to ageing when immersed in oil.
The machine is provided with a vibrator for vibrating at least a portion of said equipment, as well as with a control unit.
This study requires, inter alia, the development of a specific test bench equipped with three laser vibrometers, a vibrator and an image processing system.
Associated to a vibrating pot, an environmental chamber will enable to generate vibrations tests, combined with temperature tests.
Over 150 sensors: accelerometers, microphones, sound intensity probe, optical speed and high frequency magnetic sensor, acoustic head, vibrating pot, impact hammer, pressure sensor, etc.
These tests are carried out following 3 orthogonal axes on a vibrating pot for vibration tests or by means of a ram for impact tests.
Among promising technologies is the vibrating pot, a speaker without a membrane, which is stuck to the back of an object and uses matter to emit sound.
