Precision Analytic algorithms on Contact stiffness of parts

摘要：

　　The couplings join the various parts together to form an assembly through contact surface,which the stiffness plays an important role for the machine characteristics.Hertz contact theory constructed the relationship between preload and stiffness from a macro perspective,while MB fractal theory presented the mapping between preload and stiffness from microscopic viewpoint.A more precise contact surface model about load and stiffness is established through learning from each other and cross-linking to prepare for analyzing the whole dynamic characteristics.
