摘要
为对液动压悬浮抛光工具盘结构参数进行优化,首先通过正交试验和CFD数值模拟,利用方差分析法分析抛光工具盘各结构参数对加工区域流体动压力的大小和均匀性的显著性影响;然后使用多元非线性回归方法和遗传算法对正交试验样本数据进行优化,得出最优结构参数。数值模拟试验表明,优化后抛光工具盘产生的动压力均值和均匀性都比优化前抛光工具盘提高了30%。
Aim to optimize structure parameters of hydrodynamic polishing tools, firstly, significant influences of size and uniformity of hydrodynamic pressures in machining areas affected by polishing tool disc structural parameters were analyzed with variance analysis method by orthogonal experiment and CFD numerical simulation. Then a multivariate non-linear regression method and a genetic algorithm were used to optimize the sample data of orthogonal experiments, and the optimal structure parameters were obtained. Numerical simulation results show that the mean of dynamic pressure and the uniformity of the dynamic pressure generated by the optimized polishing tools improve 30% comparing with that of the polishing tool disks before optimization.
