The Steady Characteristics for Negative Pressure Air-Lubricated Slider Bearing with Shallow Recesses in the Rails

本文给出了一种用于磁盘机读/写功能的非接触起停式负压磁头滑块模型。通过求解修正Reynolds方程,计算出其稳态气动力特性。给出了磁头滑块与磁盘之间润滑气膜压强分布的立体图,滑块工作曲线及压力载荷随磁盘线速度、气膜厚度、减压槽深度的变化规律曲线。

This paper shows a negative pressure air-lubricated slider bearing with shallow recesses in the rails, which is used for information storage on magnetic disk media under noncontact start/stop mode conditions. The steady characteristics of the self-loading magnetic head were studied in details by solving the modified Reynolds equation.The figures of calculated results,such as the figure of 3 dimension pressure distribution of slider bearing, the figure of flying height versus relative velocity between slider bearing and disk, the figure of load capacity versus depth of shallow recesses, and the figure of load capacity versus flying height, are given out.
