摘要
介绍了计算机硬盘驱动器的振动敏感性 ,分析了硬盘驱动器在振动环境下失效的机理 ,通过实验测定了硬盘驱动器振动环境下的短时工作失效判据中阈值 [w ]。提出爆炸地震作用下硬盘驱动器工作失效的安全比距离计算方法。
The vibration sensibility of hard disk driver(HDD) is introduced, after analyzing the damage mechanism of HDD due to vibration, the threshold in instantaneous operation damage criterion of HDD under vibration environment is experimentally determined. The attenuation of seismic wave caused by structure is considered, a method predicting safety distance scale of HDD instantaneous operation damage is provided.
