摘要
从以土壤动物蚯蚓体表形态为仿生学基础的角度出发,通过仿生改型技术改变UHMWPE试件表面的形态,以标准试件为参照,设计了3种不同尺寸的仿生多孔形结构试件,并选用L9(34)表头来设计试验方案,将通过三维流固耦合分析所获得的仿生多孔试件和标准试件转动磨损过程中的等效应力、节点接触摩擦应力的分布情况与磨损试验所得数据结果进行对比分析.
From the viewpoint of soil animal of earthworm body surface form based on bionics,through the bionic modification technology to change the UHMWPE of the specimen surface morphology,with standard specimen as benchmark,three kinds of different sizes of biomimetic porous structures specimen are designed,and then using L9（34）orthogonal to design test plan,equivalent stress and node contact friction stress of the bionic porous specimen and standard specimen obtained during rotation wear process by the three-dimensional fluid-structure coupling analysis,are compared with wear test data results.
