动物驱动足摩擦学特性研究及仿生设计

Study on Tribological Characteristics of Animals' Driving Pads and Their Bionic Design

研究了蝗虫、壁虎等具有全空间运动能力的动物脚掌的形态、材料微结构及其拓扑关系和接触力学规律。结果表明,脚掌产生的摩擦力具有明确的各向异性,脚掌各部分产生的摩擦力具有自锁合的特点,脚掌材料拓扑结构也具有各向异性特征。研究结果对陆上运动车辆驱动部件(如轮胎)的设计具有重要参考价值。

The morphological design, micro-structure of the materials, its topology and contact mechanics of grass horse, gecko and beetle were studied. The results show that friction forces generated on the pads are anisotropy, the forces among the foot or tore are balanced and the topology of materials are anisotropy. A possibility to improve the frictional characteristics of tyre is suggested.
