摘　　要：针对希捷公司ST微型硬盘驱动器磁头读写臂建立了有限元模型,通过模态分析系统探讨了预载荷对磁头读写臂动态性能的影响.结果显示,预载荷引起的磁头读写臂形状改变对其共振频率有显著影响,而预载荷引起的读写臂内应力只对一阶扭转模态共振频率有较大影响,对其它典型模态共振频率的影响有限.In this preloading stress on paper, the influence of the the dynamic performance of the read/write arm is systematically studied through finite element analysis of the ST micro - drive from Seagate. It shows that the geometry shape change due to the preloading stress can largely influence the resonant frequencies of the read/write arm while the preloading stress itself has only significant influence on the first torsion mode of the read/write arm. Its influence on the resonant frequencies of the other characteristic modes is small.
