中文摘要	基于鸵鸟足结构形貌及越沙机制,以鸵鸟足为生物原型,通过对杖托进行仿生设计,研制了一种仿生越沙杖。该仿生杖托能够根据仿生杖的垂直荷载和沙土的软硬程度自动改变结构以及杖托/沙土接触面积。采用离散元软件PFC2D,对仿生越沙杖入沙过程中触沙初始状态、承载中间状态和极限承载状态进行了数值模拟,并与普通越沙杖杖托下接触力场、速度场、沉陷量和承载力的模拟结果进行了对比,结果表明仿生越沙杖具有优越的固沙限流、抗沉陷和高承载性能。
英文摘要	As an auxiliary tool for traveling,hiking stick is very useful for travelers,in particularly for desert hiking.A bionic desert hiking stick was developed inspired by the structure,morphology and excellent travelling mechanism of ostrich foot on sand.This design has a stick tray on the tip that mimics the foot pad of ostrich,which possesses excellent characteristics of san fixation and antisinkage. The structure of the bionic stick tray and the contacting area between the tray and sand could be automatically adjusted with the changes of vertical load of the stick and the rigidity of sand.Using Discrete Element Method(DEM)software PFC2D?,the interaction between the bionic stick and sand at three different work states,including the initial contacting sand state,the middle load bearing state and the ultimate load bearing state,were numerically investigated.Simulation results show that, compared with common desert hiking sticks,the bionic hiking stick possesses the excellent characteristics of sand flow fixation,anti-sinkage and high load bearing capacity.
