摘　　要：为了研究刮研对结合面刚度的微观特性,使用LI-3型表面形貌测量仪实测得到刮研表面的真实三维微观形貌,针对收集的微观表面形貌数据,运用逆向建模方法生成真实可靠的表面实体模型。采用有限元法进行静力学接触仿真分析,得到接触力、接触变形与接触刚度关系折线图,最终得出真实微表面之间的微弹性和弹性接触特性。仿真分析结果证明,刮研表面比磨削表面具有更好的接触应力和接触刚度,能够为深入开展结合面微观作用机理研究提供理论依据。In order to study the microscopic characteristics of the joint surface stiffness,the actual three-dimensional microscopic surface topography of the scraped surface was measured by using the LI-3 surface topography measuring instrument,and the microscopic surface topography data collected by the method was reversely engineered. The method generates a real and reliable surface solid model,and uses the finite element method to carry out static contact simulation analysis. The relationship between contact force and contact deformation and contact stiffness is obtained,and the microscopic elasticity and elastic contact characteristics between the real microscopic surfaces are finally obtained. The results of simulation analysis prove that the scraped surface has better contact stress and contact stiffness than the ground surface. This study can provide a theoretical basis for the in-depth study of the microscopic mechanism of bonding surface.
