采用数值方法对高刚度卧式空气静压主轴进行优化设计，并通过实验进行验证。通过数学变换，将气体润滑Reynolds方程的一般形式变换成标准的椭圆型偏微分方程形式，再以MATLAB软件中的PDE工具箱为求解器，编制迭代计算程序，实现空气静压主轴的静态性能计算。分析结构参数对主轴性能的影响，得到最优的主轴结构参数；通过实验测试了优化后主轴的轴向和径向刚度，实验结果验证仿真方法的准确性。

A numerical simulation method was presented to optimize the design of high stiffness horizontal aerostatic spindle,which was verified through experiments. The standard elliptic partial differential equations were got by converting the common gas lubrication Reynolds Equations with mathematical transformation.By using MATLAB software PDE toolbox as a solver,the calculation of static performance of aerostatic spindle was carried out through programming iterative calcula?tion algorithms.The effect of structure parameters on aerostatic spindle performance was analyzed,and the optimal structure parameters were chosen.The radial and axial stiffness of the optimized aerostatic spindle was tested,the experimental re?sults verified the accuracy of the simulation analysis method.
