BioMedical Engineering OnLine, 2006 Background In some cases, it may be necessary to combine distinct finite element meshes into a single system. The present work describes a scheme for coupling a finite element mesh, which may have curvilinear elements, to a voxel based finite element ...

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.

Optimization of bias modification and dynamic behavior analysis of helical gear system
Advances in Mechanical Engineering, 2017 A generalized finite element dynamic model of helical gear system considering time-varying mesh stiffness and loaded composite mesh error is developed. Bias modification is introduced into this model, and the corresponding time-varying mesh stiffness and

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

Bifurcation phenomena in internal dynamics of gear systems [PDF]
Applied and Computational Mechanics, 2007 The impact effects in gear mesh represent specific phenomena in the dynamic investigation of highspeed light transmission systems with kinematic couplings. They are caused of greater dynamic than static elastic deformations in meshing gear profiles.
