Ursachenforschung, Monitoring und Kompensation des Axialdrifts von rotationssymmetrischen Werkstücken auf Rollendrehvorrichtungen

In this work, the mechanical system of turning roll devices is studied and filtered with regard to possible influencing factors on the drift movement occurring during operation. The results of these fundamental investigations flow into the creation of a multi-body simulation model with which the findings are verified. The developed model test rig on a reduced scale is developed based on the observations during a technical measurement on a reel turning device in original size, the examined patent documents, the derived influencing factors in the mechanical system of the reel turning devices, as well as the performed multi-body simulations. The model test rig enables singular investigations of the various causes of the drift movement. As a result, control algorithms could be developed and implemented on the model test rig, which show that the drift movements can curatively be minimized very much. In addition, the algorithms, which access measurement values from the 3D force sensors, that have also been developed and implemented on the model test rig, offer approaches for preventive drift compensation. The investigations can be demonstrated with the multi-body simulation model and the developed model test rig, while the results can be transferred to a prototype of reel turning devices in original size and verified there. During the upscaling process from the model to the original a call back to the multi-body simulation model can be done.
