Abstract

A thorough understanding of the dynamic behavior under shock is essential to the development of new generation disk drives. In this paper, the effects of the acceleration pulse shape under conditions of different pulse widths are studied for a given resonant frequency. To emphasize the fundamental aspects of the pulse shape effects, the dynamic system investigated was a single actuator arm without inclusion of the head disk interface or suspension

硬盘跌落试验仿真中激励脉冲效应的功率谱分析
彻底了解冲击下的动态行为对新一代磁盘驱动器的开发至关重要。在给定的谐振频率下,研究了不同脉冲宽度条件下加速度脉冲形状的影响。为了强调脉冲形状效应的基本方面,所研究的动力系统是一个单独的执行器臂,不包括头盘接口或悬架
