Abstract :
This paper explores the dynamic characteristics of slim optical disk drives and the modification of their structural dynamics to reduce vibration using a simplified finite-element (FE) model. The FE model was constructed using simplified geometry and valid element types that effectively reflect the dynamic characteristics. The FE model was verified by experimental modal analysis (EMA). Design parameters were extracted and selected to modify the structural dynamics using design of experiments, topology optimization, and modal strain energy distribution. A prototype of the modified model was constructed and its anti-vibration performance was estimated using EMA and comparison of frequency response function.
