外存储器中流体动压轴承槽形结构设计与仿真

Design and Simulation of Groove Parameters of HDB for Storage Device

讨论高道密度外存储器中主轴电机的流体动压轴承中的槽形结构参数对轴承性能的影响．在仿真轴承承载能力随槽形单个参数变化的基础上，提出了一种方法，通过Ｔａｇｕｃｈｉ方法对槽形参数优化组合，然后与有限元法、耦合计算相结合，以获得具有良好轴承综合性能的组合槽形结构参数，实现了多目标设计．

Effects of groove parameters of Hydrodynamic Bearing (HDB) in spindle motor for the high density storage device on its performance are discussed. A method integrating optimization combination of the groove parameters through Taguchi Method with coupled calculation through finite element method is proposed, which is used to obtain combined groove parameters that possess favorable synthesis performance and realizes the multi object design.
