摘要： 采用逆向工程技术，完成了鸵鸟足底曲面三维重构和分区，基于离散元法和有限元法，进行了鸵鸟足底曲面/沙土相互作用数值模拟。鸵鸟足底曲面下沙土颗粒流动程度沿足宽方向大于沿足长方向，表明鸵鸟足底曲面形貌更好地减缓了鸵鸟足在沙地上的前行滑移程度。在鸵鸟足多曲面结合形貌中，第Ⅲ趾底中间凹槽面固沙限流效果最好，此区域的沙土颗粒群受力呈现网格状稳态紧固分布。鸵鸟足第Ⅲ趾底中间凹槽面数学模型的建立，为鸵鸟足底曲面仿生设计提供了重要理论依据。

Abstract: 3D model reconstruction and partition of the plantar surface of ostrich didactyl foot were achieved using reverse engineering. Discrete element method and finite element method were employed to simulate the interactions between the plantar surface of ostrich didactyl foot and sand. It was shown that the flowing extent of sand particles under the plantar surface along the foot breadth direction was greater than that along the foot length direction. This may indicate that the plantar surface morphology of ostrich foot can preferably retard the slippage during ostrich foot moving ahead on sand. Within the plantar surface of ostrich foot, the middle groove in the third toe plantar surface has most obvious effect of sand flow fixation, under which the forces on the sand particle groups present the grid-patterned stable tight distribution. A mathematical model of the middle groove in the third toe plantar surface was established, which may provide theoretical reference for bionic design of the plantar surface of ostrich foot.

Key words: bionic engineering, didactyl foot of ostrich, plantar surface morphology, sand flow fixation, numerical simulation
