本文通过基于Boltzmann方程的广义润滑方程，研究了超薄间距浮动磁头滑块的动力学特性，并与两种极限情况：轴承数近似为θ → 0和θ → ∞进行了比较。在极限条件下，这些近似与数值结果吻合得很好。特别地，我们发现了一种近似，它能定量地解释阻尼系数的特性和相应的不稳定现象。
This paper investigates the dynamic characteristics of flying head sliders with ultra-thin spacing through a generalized lubrication equation based on the Boltzmann equation, and compares them with two limiting cases: approximations for bearing number ∧ → 0 and ∧ → ∞. These approximations agree well with numerical results in the limiting conditions. In particular, the approximation for ∧ → ∞ is found to quantitatively explain the characteristics of damping coefficients and correponding unstable phenomena.
