The project “Integrated Sensor Technology for Intelligent Large-Scale Rolling Bearings”, ISiG for short, is gaining further momentum in its second phase. From 14 to 17 April 2026, joint experiments were conducted at the IMKT as part of the DFG Priority Programme 2305 on Sensor-Integrating Machine Elements (SiME).
The aim of the joint project is to connect different smart machine elements, combine their measurement data in a shared gateway, and evaluate these data for condition monitoring. For this purpose, a test rig was provided at the IMKT, where the measurement technology developed in the laboratory was investigated in a realistic component test.
In the experiments, three sensor-integrating machine elements were operated jointly: a sensor-integrating jaw coupling from TU Dresden [link], an intelligent radial shaft seal (RWDR) from RPTU [link], and the sensor-integrating rolling bearing developed at LUH [link to the university and, below, links to IMS and IMPT?]. Relevant condition variables were recorded, including torque at the coupling, temperatures in the RWDR, as well as strains and temperatures in the rolling bearing within a joint gateway. The measurement system was integrated during operation of the test rig and thus provides a basis for enhanced condition monitoring.
During the three-day experiments on the Mechanical Engineering Campus in Garbsen [link], initial experience with the joint operation of the systems was gained and successful test runs were carried out. The results will be presented at the SiME Congress, which will take place in Darmstadt on 15 and 16 September 2026.
