仿生功能表面抗冲蚀磨损仿真分析

In order to improve anti-erosion performance of mechanical surfaces, simulation experiments were designed using table L9(34) based on method of orthogonal experiment optimization design. And, the finite element analysis software FLUENT12.1 was utilized to study the anti-erosion performance of three types of samples, namely, the smooth sample, the square sample, the V-shaped sample and the arc-shaped sample. Method of poor analysis was applied to deal with the test data. Simulation results show that the V-shaped sample have the best anti-erosion performance in the test. And, compared with the smooth sample, anti-erosion performance of the V-shaped sample with feature size of 4 mm and spacing of 2 mm improve about 62.2%.
