摘要

硬盘驱动器(hdd)在操作冲击下的飞行稳定性变得越来越重要，因为磁头/磁盘接口的飞行高度已经降低到10纳米以下的飞行高度范围。本文研究了滑杆在工作冲击作用下的动态响应。采用“离散刚度法”对空气轴承进行了6个线性弹簧的建模。

A numerical study of the operational shock response in a hard disk drive using the discrete stiffness method

The flying stability of hard disk drives (HDDs) during operational shock has become increasingly more important as the flying height of the head/disk interface has been reduced to the sub-10 nm flying height regime. In this paper, the dynamic response of a femto slider due to operational shock is investigated. The air bearing is modeled with six linear springs using the “discrete stiffness method”.
