Abstract

This study was performed to evaluate the dynamic behaviour of four different propeller shafts on the basis of mode shape, frequency and damping in response to an excitation in the frequency range of 275--400 Hz. The differences among the four shafts were characterized by the damping treatment. One shaft had no damping treatment, another shaft had an old style of cardboard liner, another shaft had a new style of cardboard liner and the last shaft had a foam damping treatment. The modal testing of the propeller shafts was conducted at the University of Windsor/DaimlerChrysler Automotive Research and Development Centre. Two shakers were used to excite each shaft while it was supported in the free-free condition. Four measurements were taken around the circumference of each shaft at five different axial locations using modal accelerometers. Data was collected using the LMS Roadrunner 32 system and analyzed using the LMS Modal Analysis module. Theoretical calculations were completed and a finite element model was developed in order to compare these results with experimental findings. Validation tools were used to support the modal model and to validate the measurement system. It was concluded that the propeller shaft with the foam damping treatment was the only shaft that did not exhibit resonant behaviour in the 275--400 Hz and demonstrated higher damping values than the other three shafts. Good correlation was obtained between finite element results and experimental results.* *This dissertation includes a CD that is compound (contains both a paper copy and a CD as part of the dissertation).
