Gear tooth mesh stiffness: A comparison of calculation approaches
Mechanism and Machine Theory, 2016 Abstract This work compares spur gear tooth mesh stiffness calculations using two approaches. The first is a common approach from the literature that calculates the mesh stiffness by dividing the mesh force by the mesh deflection, which we call the average slope method.

Dynamic Analysis of Gear Systems with Dynamic Mesh Stiffness and Time- Varying Bearing Stiffness
Nonlinear DynamicsAbstract In this study, a novel analytical model for dynamic mesh stiffness of spur gears is developed using variable cross-section beam theory, explicitly accounting for driving speed effects. The dynamic mesh stiffness is determined by applying the modal superposition method to analytical model equations, and subsequently validated using both

Study on the Spalling Fault Degradation Mechanism and Dynamic Model of Gear Tooth Surfaces
Jixie chuandong, 2023 Under the action of alternating load, the initial crack on the gear tooth surface would inevitably initiate and gradually evolve into spalling and other faults. It has a serious impact on the transmission system.

Advanced Functional Materials, EarlyView.Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.
