Improved Spring Fractal Model for Normal Static Elastic Stiffness of Stationary Contact Interface
摘要
Abstract
The solution for normal contact static elastic stiffness of two interacting asperities was derived according to Hertzian contact theory. The analytic expressions for joint interface gross normal contact static e-Jastic stiffness with a certain condition and total load with a given one were deduced from the improved fractal geometric theory. The formulae for interface static elastic rigidity and total load were given in terms of an empirical power-law relationship of the form about machine tool joint interface normal deflection-pressure from reference[10]. The calculations of engineering rough surface make clear that the normal total stiffness-load curve is in basic agreement with the experimental conclusion stated by reference[10]. The improved fractal geometric theory will pave a firm foundation for further fractal studies as well as identifying joint interface's parameters.关键词
