项目摘要

In order to understand the friction mechanism in the case of contact of two bodes which have complicated shape and non-linear elastic properties, a new visualization method of partial slip is proposed by combining a tribosystem, VTR, correlation method and computer graphics as a "Visual-Tribosystem".By using this method, several studies were carried out. The obtained results may be summarized as follows :(1) Results of visualization show increase of slip area at the contact surface of rubber with increase of tangential coefficient in the real time.(2) It is shown that macro-slip occurs when stick area observed by visualization becomes zero, which means that partial slip visualization provides good enough resolusion.(3) From the results of visualization, the distribution of partial slip at the interface of contacting surfaces was obtained, and it indicated that the partial slip increased as a result of increasing the tangential coefficient.(4) From the analysis of effect of inclusion at the contact interface on static friction coefficient, it is clear that static friction coefficient decrease with increasing of inclusion size, and static friction coefficient changes in depend on position of inclusion at the contact interface.(5) Propagation direction of micro slip area at the contact interface can be classified into two types such as from around to center of contact area and front edge to behind of contact area.(6) Static friction coefficient and change of micro slip area in the case of contact of two bodies which have complicated shape such as square, triangle, Rectangular, circle, concave and spherical are clarified.
为了了解具有复杂形状和非线性弹性性质的两个刚体接触情况下的摩擦机理,提出了一种新的局部滑移可视化方法,该方法将三体系统、录像机、相关方法和计算机图形学结合为一个“可视化三体系统”,并利用该方法进行了若干研究。结果表明:(1)可视化结果实时显示出橡胶接触面上滑移面积随切向系数的增大而增大。(2)可视化观察到的粘结面积为零时发生宏观滑移,部分滑移可视化提供了足够好的分辨率。(3)由可视化结果得到了接触面上部分滑移的分布,表明部分滑移随切向系数的增大而增大。(4)从接触界面夹杂对静摩擦系数的影响分析,结果表明,静摩擦系数随夹杂物尺寸的增大而减小,静摩擦系数随夹杂物在接触界面上的位置变化而变化。(5)接触界面微滑移区的传播方向可分为从周围到接触区中心和从前缘到接触区后方两种类型。(6)阐明了方形、三角形、矩形、圆形、凹面和球面等复杂形状物体接触时的静摩擦系数和微滑移区的变化。
