Abstract: In order to study the contact characteristics of the sliding pin and the driving shaft hole in the three-prong sliding universal joint, combine the actual contact between the sliding pin and the driving shaft hole, based on the M-B fractal model, a fractal contact model of the sliding pin and the driving shaft hole considering the effect of friction is derived and established. Through MATLAB numerical simulation analysis, the influence of each parameter on the contact load-bearing performance is obtained. The results show that: reducing the fractal roughness, friction factor, increasing the material characteristic parameters, and the appropriate contact length, fractal dimension, and material hardness are more helpful Improve the contact bearing capacity and improve the mechanical properties between the contact surfaces.The research results of this model provide a theoretical reference for further research on the contact characteristics of the sliding pin and the driving shaft hole.
Key words: sliding pin for driving shaft hole; contact load; fractal theory
