Abstract
All automotive mirrors undergo very strict vibration tests before being installed in an automobile. The aim of this project was to use the finite element method to predict the vibration performance of a mirror prior to the tool being manufactured, thus reducing or eliminating all expensive and time consuming modifications to the tool. The finite element predictions were compared with equivalent experimental results. Good correlation was achieved between the predicted and measured natural frequencies of the mirrors. An investigation of the damping properties of the materials was carried out in order to predict the magnitude of displacement of the mirror. It was concluded that the most accurate way to model damping was using the damping ratio. Damping ratios of certain models were calculated and used to perform harmonic analyses. In certain cases good correlation was achieved between the predicted and measured displacements.
