Life and Reliability Examination of Internal Gear and External Gear Contact in Gear Mechanisms
8th International Students Science Congress Proceedings BookGear mechanisms are indispensable mechanisms used in many machines as power and motion transmission elements. What is expected from gear mechanisms is that they can achieve a high cycle rate in a small area and function for a long time. In this study, safety, life and reliability comparisons of gear mechanisms in terms of root and flank safety in ...

Advanced Intelligent Systems, EarlyView.Musculoskeletal humanoids exhibit rich biomechanical properties that remain insufficiently unified in prior discussions. This article systematically categorizes muscle characteristics into five properties: redundancy, independency, anisotropy, variable moment arm, and nonlinear elasticity, and analyzes their combined effects on control.

Gear mesh compliance modeling [PDF]
A computer model has been constructed to simulate the compliance and load sharing in a spur gear mesh. The model adds the effect of rim deflections to previously developed state-of-the-art gear tooth deflection models.
