New equipment for acoustic emissions and a seal test rig have been designed and installed in relation to WP5. The acoustic emission equipment consists of an AE sensor, preamplifier and one channel of an ASIP-2 (dual channel acoustic signal processor). With this equipment multiple AE signals and features can be measured. The seal test rig shown in the image below is intended to investigate failure mechanisms, detection methods and remaining useful life prediction of the seals for hydraulic cylinders. The test arrangement consists of a pressure chamber connected to an electromechanical cylinder.

For questions concerning the equipment get in touch with WP5 leader Thomas Meyer.
