为了研究粗糙表面的复杂接触力学行为
提出了一种关于微观两粗糙表面接触的有限元分析方法.通过3D粗糙表面的数字化表征方法
获得了具有不同统计特征的高斯或非高斯粗糙表面
在此基础上
通过自下而上的三维建模与六面体网格划分
构建了两粗糙表面接触的精细有限元分析模型.在不同法向载荷的作用下
分析了微观结合面的变形、接触压力、真实接触面积等接触特征及其加载卸载特性
揭示了结合面的力学行为规律
为微观粗糙表面的性能预测提供了一种有效的途径.
A finite element analysis for simulating the contact performance between two micro-rough surfaces is proposed. The numerical characterization of Gaussian or non-Gaussian rough surfaces is introduced to lay the foundation of this analysis. Then bottom up solid modeling and hexahedral meshing lead to an accurate finite element model. The normal deformation
nominal contact pressure
real contact area
contact pressure distribution of the interface under different normal loads are discussed and their loading/unloading characteristics are investigated to reveal the mechanical behavior laws
which provides a new approach to predict or evaluate the performances of micro-rough interfaces.
