摘要
本文采用微分离散有限差分法求解滑流条件下的修正雷诺方程.离散后的三对角线性代数方程组用ADI方法求解.本方法适用于任意几何形状、尺寸、姿态角的多轨窄式磁头滑块的气动力计算,并不受大压缩数的限制.计算结果包括即时给出的压强分布立体图.
The modified Reynolds equation under slip-flow condition is solved inthis paper, using finite difference method of differential discretization. The discretized tri-dia-gonal linear algebraic equations are solved with ADI method. This method can calculate the gasdynamic forces of the multiple-rail magnetic headslider of various geometric sizes and pitching angles, and is not confined by the big compressibility numbers. The results of calculation include the load carrying capacity, the centre of lift, the pressure distribution and immediately presented curved surface of pressure distribution.
