1.前言本文以小型磁盘装置JK-811的圆形浮动块为例,用数值计算方法,对浮动块的静态特性进行了分析。分析中,假定空气是可压缩流体,空气的惯性力可以忽略不计,以及空气膜厚度具有弯曲的表面和有限的宽度。影响浮动状态的各因素有:浮动块的外形、浮动块支撑机构、浮动块负荷机构、浮动块表面状态、盘表面的振动以及使用环境。设计浮动块时须注意:1)加强浮动块和磁盘之间流动的气垫的刚性,以提高固有的振动频率;2)提高空气 1. Preface In this paper, a small disk device JK-811 circular slider as an example, the numerical calculation method, the static characteristics of the slider were analyzed. In the analysis, the air is assumed to be a compressible fluid, the inertia of the air is negligible, and the air film thickness has a curved surface and a finite width. Factors that affect the floating state are: the shape of the slider, the slider support mechanism, the slider load mechanism, the surface condition of the slider, the disk surface vibration and the use of the environment. When designing a slider, care must be taken to: 1) increase the rigidity of the air cushion flowing between the slider and the disk to increase the inherent vibrational frequency; and 2) increase the air
