摘　　要：基于有限元法对典型计算机硬盘模态及瞬态响应进行了研究。研究表明:装配体中的零部件的固有频率会互相影响;最敏感的区域为悬架边缘即安装磁头的位置。因此,可以在不影响磁头读写的情况下,对磁头进行加固增加抗振能力,对提高计算机硬盘驱动器的抗震设计具有积极意义。Based on the finite element method, the model of the typical computer hard disk and its transient response are studied. The results show that the natural frequency of the assembly parts will affect each other; the edge of the suspension is attached to the head of the position. Therefore, without of affection of its work, the head of the disk could be reinforced in order to improve the shock resistance of the hard disk drive. It is very useful for the design of shock resistance and security of the computer hard disk.
