摘要

在车载环境下，冲击和振动会对工作中的硬盘造成传输中断甚至损坏。采用抗冲击振动性能强的硬盘以及合理的减振装置可以使设备稳定地工作。文中通过实验测试出某型号硬盘开启主动保护的激振频率的范围，针对实验数据及车载情况选用钢丝绳减振器，通过简化的动力学模型，确定了减振器型号以及隔振效率，并采用合理的安装方式，设计出结构简单，适应性强的硬盘隔振系统。

Abstract

In the vehicle-loaded environment, the transmission of data would be interrupted and the working disk would be damaged by the vibration and shock. The device may work stably by using hard disk with strong anti-vibration performance and reasonable damper. This article tests out the exciting frequency range of a hard disk which can activate the active protection by experiments, chooses wire rope shock absorber according to the experimental data and its application environment. This paper designs simple structure and adaptable vibration isolation system of hard disk by simplifying the dynamics model, figuring out the efficiency of the absorber and using seasonable installation.
