将区域分解法应用于织构表面的流体动力润滑分析。数值模拟表明，与传统的求解方法相比，区域分解法的计算规模和计算效率都有显著提高。通过对不同类型织构分布的一系列数值分析，找到了平板轴承和阶梯轴承的最佳织构表面模式。对典型织构表面模式的实验结果表明，区域分解法的计算规模和计算效率都有显著提高实验结果表明，激光毛化阶梯轴承的承载能力预测与实验结果吻合较好。
Domain decomposition method was applied in the hydrodynamic lubrication analysis of textured surfaces.Nurneric simulation indicated that the computable scale and calculating efficiency was improved remarkably comparing with conventional solution method.The optimal texture surface patterns of the plate bearing and the step bearing was found through a series of numerical analyses which include different types of texture distribution patterns.The experiment of representative patterns of step bearing was carried out.Experimental results indicated that the prediction of load-carrying capacities of laser textured step bearings accorded with experiment results.
