Abstract

A new suspension model of an optical pick-up actuator is developed. This model is very stable and easily manufactured owing to its specially designed geometry. In designing the suspension, the first two natural frequencies are kept lying in a certain range and sub-resonance frequencies are made as high as possible. The vibration and sensitivity analysis needed for optimal design is based on a simplified beam model of the bobbin-suspension structure. The investigation of the strain energy distribution in each vibration mode appears to be very useful.
