Mechatronic Model for Traversing Rod Longitudinal Vibration Analysis

The paper deals with analysis of vibration of traversing rod on rotor spinning machines. The rod is part of winding system and it should provide a precise motion in order to ensure quality package. However the rod is subject of dynamic load that excites detrimental longitudinal vibrations. In order to better understand the behaviour of the rod a mathematical model in Matlab/Simulink is used to describe the system. The traversing rod was described using finite element method while a dq model was used for the permanent magnet synchronous motor description. To verify the mathematical model the simulation results were compared to experimental data. Results from the simulation proved the model to be well suited for the system description.
