磁盘、磁头飞行特性测试仪是检测磁盘盘面特性、磁头飞行特性及其飞行间隙的专用设备,而空气静压精密轴系是该设备的关键部件。本文着重对空气静压精密轴系的结构设计及其静态性能、动态性能测试作了较详细的论述,通过理论与实验对比,验证设计的合理性和计算的正确性。尤其是在实验的基础上建立了轴系角刚度理论数学模型和实验数学模型,为研究轴系角刚度提供了理论与实验依据。 Disk, head flight characteristics tester is to detect the characteristics of the disk surface, head flying characteristics and flight space dedicated equipment, and precision air shaft hydrostatic shaft is the key components of the device. This article focuses on the structural design of the hydrostatic precision shaft system and its static performance, dynamic performance test in more detail discussed, through theoretical and experimental comparison, to verify the rationality of the design and calculation accuracy. In particular, based on the experiment, the mathematical model and the experimental mathematical model of shaft stiffness are established, which provide the theoretical and experimental basis for the study of shaft stiffness.
