Abstract

The goal of this study is to develop an FE model for bobbin holders which wind the fiber. It comprised 25 components. Under mechanical assumption, it was simplified and approximated to 8 components. The equivalent stiffness of three types of bearings in a bobbin holder were obtained using compression tests. The main natural frequency of a precision model without a chuck was 17.82 Hz in mode 1 and 102.95 Hz in mode 3. The results of simulation and experimental analysis by modal testing were very similar within 2%. To obtain a more precise FE model, optimization for equivalent stiffness of the 6011 bearing was applied to modal analysis in the ANSYS. Finally, an FE model of a bobbin holder considering vibrations was developed.


Keywords: Modal analysis, Bobbin holder, FE model, Vibration, Optimization
