The results show that the microstructure of ventra1 scale for python was composed of micro-convex and plank structure that was periodically arranged, it was mensurable and could be described by 9 characteristic parameters. Its surface was different in their forward and backward lean angle. The frictional coefficient of the ventra1 scale had closely relationship with moving direction, it decreased with the increasing load. The value of the frictional coefficient was about 0.07. The frictional coefficient while python moved backward and laterally were equal, and that was 33% more than that moved ahead. The frictional force of the ventra1 scale surface was caused by mechanical tooth function of micro-convex, acting intermolecular force and material's elastic hysteresis. The difference of forward and behind bevel for micro-convex was the anisotropy reason of frictional force.
结果表明:腹鳞表面的微观结构由指状微突体和板结构部分周期排列而成,其结构可用9个特征参数定量描述;腹鳞表面摩擦力由分子作用力、表面微突体的犁沟力、楔形作用力以及材料弹性滞后共同引起;腹鳞表面的摩擦系数在0.07左右并与运动方向有关,摩擦系数随载荷增加而减小;后向运动及左、右侧向运动时摩擦系数基本相等,比前向运动时高33%左右;腹鳞表面微突体不同方向上倾斜角度的差异是引起摩擦各向异性的主要原因。

Single factor experiments were done with the factors including the width of protrusion and the trolley's velocity, which showed that the surface frictional coefficient decreases with the width of protrusion increasing, and doesn't change with the trolley's velocity changing, which was consistent with the results of the orthogonal experiment. A theoretical model of the horizontal projection of a corrugated bionic surface's contact area was built, which showed that the contact area's horizontal projection decreases with width and interval increasing respectively and that the ratio of the contact area's horizontal projection and the vertical load decreases with the vertical load increasing. It indicated that the surface frictional coefficient decreases with the above three factors increasing respectively. Finite element modeling and analysis of interactions of a plate and soils was done using ANSYS, which showed that the plate frictional coefficient is little relative to soil elastic modulus and decreases with vertical surface pressure and that trolley's pull and vertical displacement of bionic surface's control pilot keep constant almost during the plate being pulled. Finite element modeling and analysis of interactions of a corrugated bionic surface and soils was done using ANSYS, which showed that surface frictional coefficient is little relative to soil elastic modulus and decreases with bionic surface's structural parameters and vertical pressure increasing. However, the three factors all didn't affect the surface frictional coefficient remarkably on the condition of 90% dependability. For the first time, bionic surfaces were applied to screw piles, which formed bionic screw piles, and the contrast experiments showed the bionic screw pile had certain resistance-decreasing effects.
建立了波纹型仿生曲面与土壤的接触面积的水平投影的理论模型,表明接触面积的水平投影A随着波纹型仿生曲面突起宽度、两相邻突起间距的增大而减小,接触面积的水平投影与波纹型仿生曲面表面垂直载荷之比随着波纹型仿生曲面表面垂直载荷的增大而减小,进而得出仿生曲面摩擦系数随着波纹型仿生曲面突起宽度、两相邻突起间距以及表面垂直载荷的增大而减小;利用ANSYS软件对平板与土壤的相互作用进行了有限元建模与分析,表明平板摩擦系数与土壤弹性模量关系不大,而随着表面垂直载荷的增大而减小;平板牵引过程中台车牵引力和仿生曲面控制节点垂直方向位移基本保持不变;利用ANSYS软件对波纹型仿生曲面与土壤的相互作用进行了有限元建模与分析,表明波纹型仿生曲面系数在一定范围内基本不受土壤弹性模量的影响,随着波纹型仿生曲面突起宽度、两相邻突起间距以及表面垂直载荷的增大而减小,但在可信度为90%的前提下,三个因素影响都不显著;首次将波纹型仿生曲面应用于与土壤作用方式以挤压为主的螺旋桩,形成仿生螺旋桩,并与普通螺旋桩进行了沉桩对比试验,表明波纹型仿生曲面应用于螺旋桩桩体表面具有明显的降阻作用。
