| 摘 要： | 基于蚯蚓体表背孔及机体耐磨特性,设计了通孔试件和普通平板试件,进行了摩擦磨损特性对比试验。试验结果表明,具有通孔结构的仿生试件有明显的耐磨效果,在润滑条件下有显著的减阻效应。结合磨损形貌、润滑状态及摩擦过程三维有限元模拟,分析了通孔结构对摩擦界面接触、润滑等摩擦因素的直接影响和对试件耐磨性的多因素耦合作用机理,为摩擦副耐磨技术的开发提供了理论基础。

| Abstract: | Based on the back pore distribution and wear-resistance characteristics of the earthworm, through-hole structures and flat samples were designed and an experiment was performed to compare their friction and wear characteristics.The experimental results show that the samples with through- hole structures have evident wear-resistance ability and obvious drag reduction effect under the lubrication conditions.Combining the wear appearance,lubrication states and three dimensional finite element simulation of the... |
