Suspension Wires Parameters Analysis of Structural Resonance of 3-Axis BD Optical Head Actuator

Abstract:

Force distributions on coils have been simulated with vector magnetic analysis. Resonance of 3-axis optical head actuator has been obtained for 50.5Hz, 54.8Hz and 205.2Hz in focus, track and tilt directions respectively with ANSYS modal solution. Resonance frequency is mainly determined by suspension wires, and Wire-angle, length, radius and sections are main wires’ parameters. The effects of suspension wires’ parameters on resonance response has been gotten and discussed.
