Modeling a drum motor for illustrating wearout phenomena

In this contribution, a model of a drum motor is presented. This model was designed for description of dynamic behaviour of the drum motor as well as for the possible implementation of several wearing phenomena. Using this model, a better understanding of wear and tear phenomena has been achieved by carrying out a considerable number of simulation runs using different operational and wearing conditions. Using this information, important knowledge about detection of wearout signs was able to be gained. Often, mathematical models with different levels of detail are used. In these cases, it may be a difficult task to obtain reliable parameters. In this paper, we present three different approaches for establishing a model structure and for the determination of needed parameters. This way, we were able to define every part of the model with an appropriate level of detail and equip them with adequate parameter values.
