Research of Fractal Contact Model on Contact Carrying Capacity of Two Cylinders'' Surface
两圆柱体表面接触承载能力的分形模型研究

A new fractal contact model of two cylinders is set up through combining the M-B fractal contact model and traditional Hertz model.The model shows that the load and area meet exponential relationship.The exponent is not only affected by the fractal dimmension,but also by the contact radius and contact style.After the contrastive analysis and calculation examples of contact stress with the M-B model and Hertz model,it is proved that the fractal contact model of cylinders' surface can correctly reflect the st...
