摘　　要：根据试验优化设计理论,利用L27(313)三水平正交表设计试验,对具有凹坑形、凹槽形、圆环形仿生形态表面的试件进行冲蚀磨损试验研究,运用极差分析处理试验数据,得到三种表面形态试件的冲蚀率与各试验因素之间的关系。结果表明:试验因素对冲蚀率的影响程度由大到小依次为砂子目数、转速、喷砂量、形态;冲蚀率随着目数、转速的增大而增大;所有一级交互作用中,形态和喷砂量之间的交互作用对冲蚀率的影响最大,目数和转速之间的交互作用对冲蚀率的影响最小。The sand blasting erosion wear of samples with concave,flute and traffic circle bionic surface configurations was investigated by experiments.The optimal experimental design theory was employed and a three levels orthogonal table L27（313） was adopted to arrange the experiments.Experimental data was processed by range analysis.The relationships between the erosion rate and the experimental factors,such as the rotation speed of sample,surface configuration,sand size（mesh） and blast rate,were obtained.The significances of the effects of these factors on the erosion rate are in the order：the sand mesh,rotation speed of sample,sand blast rate and surface configuration.The erosion rate increases with the rotation speed and sand mesh.Among all primary interactions,the effect of the interaction between configuration and sand blast rate on the erosion rate is the strongest one,while that between the sand mesh and rotation speed is the weakest one.
