Research of Fractal Model of Tangential Stiffness for Contact Surface of Cylindrical Gear with Variable Hyperbolic Circular-arc-tooth-trace by Bai Qingsong, Hou Li, Wu Yang, Luo Lan, Wei Yongqiao

“…Based on the fractal theory and Hertz contact theory,the establishment of fractal model for tangential stiffness for contact surface of cylindrical gear with variable hyperbolic circular-arc-tooth-trace（ VH-CATT） is presented. This model is obtained by introducing the equation of critical contact area of elastic and plastic deformation of asperity and employing the surface contact coefficient of two ellipsoids to modify the asperity distribution function. …”
