摘要

研究微织构曲面结合面上的表面形貌参数对曲面结合面接触阻尼的影响。分析结合面阻尼来源，建立了结合面单个微凸体阻尼的数学模型。进一步的，以平面微凸体的分布密度函数为理论依据计算曲面接触微凸体的数量，并研究曲面结合面上织构密度、材料特性参数，以及施加的动态载荷的频率和幅值对接触阻尼的影响。经过研究及实例分析结果表明：织构密度越高，曲面结合面间的接触阻尼越小；随着材料特性参数的增大，法向接触阻尼越来越大；伴随振动频率加大，相同的载荷下接触阻尼逐渐减小；动态变形幅值越大，接触阻尼越大。

Abstract

The effect of surface morphology parameters on the contact damping of miero textured surface was studied. The damping source of the joint surface is analyzed

and the mathematical model of the damping of a single micro convex body on the joint surface is established. Further

based on the distribution density function of planar micro bumps

the number of surface contact micro bumps is calculated

and the effects of texture density

material characteristic parameters

frequency and amplitude of applied dynamic load on contact damping are studied. The results of research and example analysis show that the higher the texture density is

the smaller the contact damping between the surfaces is. With the increase of material characteristic parameters

the normal contact damping increases. With the increase of vibration frequency

the contact damping decreases gradually under the same load. The larger the dynamic deformation amplitude is

the greater the contact damping is.
