| Popis: | This study introduces a simulation approach that can be utilized in the detection of abnormalities in the behaviour of machines. The approach is based on the utilization of a detailed multi-body simulation model. In this study, the approach to detect abnormalities is applied to the study of a reel. The reel under investigation is used at the finishing end of the papermaking process and it consists of a number of subsystems including hydraulics, electrical drives, and mechanical parts. In the reel, mechanical parts are coupled by joints, contacts, and friction. The symptoms of the faults are generated using the variables which can be measured from the reel. When using a traditional component level monitoring method, the faults in the process often cannot be recognized. However, in the proposed multi-body simulation approach, the supervision of a machine can be focused on the functionality of the entire process, whereas detection of faults can be carried out without the use of additional instrumentation. When the multi-body simulation approach is used, the modelling of a machine can be carried out in a straightforward and systematic manner including the dynamic coupling between the subsystems of a machine. |
