Effect of Surface Morphology on Dynamic Characteristics of Cam-Follower Oblique Impact System

Effect of Surface Morphology on Dynamic Characteristics of Cam-Follower Oblique Impact System

The effects of the fractal characteristics on the dynamic characteristics of the oblique impact system are studied via considering the normal contact stiffness with fractal dimension parameter of the microstructure of the interface in this paper. The normal distribution is used to describe the trend...
