... contact rolling bearings rolling friction Rigid-link mechanisms consist of multiple parts (links) and interfaces (joints) and are used to transfer motion and forces from an input to an output ( 1 ). The performance of pin joints, sliders, gears, and cams is compromised due to friction, which...

...Shuyun Jiang; Shufei Zheng This technical brief presents a dynamic model based on the traditional transfer matrix method (TMM) and Jones–Harris nonlinear rolling bearing model to study the effects of the extended structure parameters on the vibration behavior of a high-speed motorized spindle...

...K. Sunil Kumar; Rajiv Tiwari; P. V. V. N. Prasad The long fatigue life is the one of the most important criterion for the design of rolling bearings, however, due to complex and diverse internal geometries, each type of rolling bearings require a different design formulation. To increase the life...
