Paper Title:
Design of Red High-Definition NVD Mecha and Vibration Analysis
  Abstract

The problem considered in the paper is the structure design and modal analysis of Mecha in HD-NVD player. Regarding general DVD player, the influence on pickup from structure designs of spindle motor and base, assembly accuracy etc. have already been solved. But for HD-NVD player, as the speed of spindle motor working in the range from 3000 to 7000 r/m, so the these influence on pickup above correlative element have to be solved by complicated analysis. Through using ALGOR to design and analyze Mecha, obtained the structure dimension of base and modal characteristic, found its material property effecting greatly on the vibration of Mecha. With the increase of material rigidity in the base and motor stator, the system rigidity increases, then the vibration of system decreases. The result indicates that the Mecha designed and analyzed by ALGOR can meet the operating demand of HD-NVD player.
