Abstract
In order to precisely calculate normal contact stiffness (NCS), this paper discusses the fractal model to calculate NCS for spheroidal contact bodies considering friction factor. The numerical results show that the relationship between NCS and normal load is direct or inverse ratio decided by the value of fractal dimension; as fractal dimension, material propertied parameters and curvature radius increase, NCS adds; as friction coefficient and roughness amplitude rises, NCS falls instead; It is effective to increase NCS by choosing the internal contact, improving surface quality of contacts and raising the yield strength of the softer material.
