摘要：

基于对起伏和凹凸不平的表面微观几何学形貌统计分析,考查衡量微接触点的2个弹塑性变形区域,建立机床支撑地脚结合部的实际接触面积、法向接触负载与法向接触刚度的理论解.该理论解综合考虑了材料的弹性、弹塑性与塑性变形规制.计算及分析结果显示：地脚结合部的实际接触面积、法向接触负载和法向接触刚度均随着混凝土地坪与标准平板之间间距的减少而增长,但随着塑性指数的扩大而上升.微接触点高度的概率密度关乎结合部法向接触参数的程度最大.通过有限元仿真对地脚结合部法向接触参数辨识结果进行验证,计及地脚参数的有限元模型得到的谐响应分析和法向接触刚度结果与试验结果一致.结合部法向接触参数的理论考究以及仿真分析为粗糙表面接触特性的扩展探索奠定了基础.
Abstract:

The theoretical solutions for the true contact area, normal contact load and normal contact stiffness were constructed in the support ground foot joint interface in machine tools by taking account of two elastoplastic deformation zones of microcontacts based on statistical analysis of wiggly and jagged surface micro geometric morphology.  These theoretical expressions can comprehensively deal with the  deformation mechanism of elastic, elastic plastic and plastic material. The calculation and analytical results show that the real contact area, normal contact load and normal contact stiffness in ground foot joint interface  increase with the decreasing separation between concrete ground and standard panel, while they all improve with the adding plasticity index. The probability density of microcontact height has the influenced normal contact parameters in joint interface most. The finite element simulation was applied to confirm the normal contact parameters identification results in ground foot joint interface. The harmonic response analysis and normal contact stiffness results from finite element model are consistent with the experimental ones using ground foot parameters. The theoretical study and simulating analysis of normal contact parameters in joint interface  provide a foundation for the further research of the contact characters between harsh surfaces．
