Simulation and analysis of the model of calculating contact tangential stiffness between cylinders joint interfaces by MATLAB

摘要：

　　Contact tangential stiffness is an important parameter affecting the dynamics performance of contact bodies.To accurately calculate contact tangential stiffness between two cylinders joint interfaces, the fractal model of contact tangential stiffness between two cylinders joint interfaces is established based on the reasonable expansion of the existing fractal model and the early stage of research results.Simulation results by the software MATLAB show that: this model can correctly reflect the conclusion influenced by the parameters of fractal dimension, roughness amplitude and material properties parameters, so the model is improved true in theory.The establishment of the model laids the foundation for the following calculation of contact tangential stiffness about gears and cylindrical bearings and gives a new theory supplements to contact dynamics research.
