Generalized Stiffness Gear-Mesh Matrix Including EHD Stiffness

ASME/STLE 2007 International Joint Tribology Conference, Parts A and B, 2007
This paper presents a method to compute gear mesh stiffness based on the EHD behavior by combined finite element solution of the Reynolds Equation with the elastic contact model. It is shown that this solution requires iterative procedure to balance the computed pressure profile with the external nominal transmission load.

Calculation of Gear Meshing Stiffness Considering Lubrication

Journal of Tribology, 2019
Abstract Gear meshing stiffness is the key parameter to study the gear dynamic performance. However, the study on the calculation of gear meshing stiffness considering lubrication, especially mixed lubrication, is still insufficient. Based on the three-dimensional linear contact mixed elastohydrodynamic lubrication model and the contact ...

An improved analytical model for gear mesh stiffness calculation

Mechanism and Machine Theory, 2021
Abstract Time-varying mesh stiffness is considered the primary excitation in gear vibrations. An accurate evaluation of mesh stiffness is of great importance when studying gear vibrations. Based on contact mechanics and gear engagement principle, we propose an improved analytical model to determine gear mesh stiffness.

Gear Mesh Stiffness and Damping Co-simulation

2020
In this paper it is described a co-simulation between a multibody dynamics system (built in MSC.ADAMS®) and a gear mesh stiffness and damping model implemented by means of block diagrams (MATLAB/Simulink®). The total knowledge about the gear pair model is valuable when modelling and analyzing dynamic systems sensitive to the mesh varying properties ...

Scalable Mesh Deformation with Controllable Stiffness

2013 International Conference on Computer-Aided Design and Computer Graphics, 2013
This paper presents an efficient and physics-plausible deformation algorithm. A simplification is first conducted on the original mesh, then the deformation of the simplified mesh is passed to the original mesh to obtain an initial result. Then a set of optimal rigid transformations are computed to preserve the shape features and control the surface ...

Dynamic Analysis of a Multi-Mesh Gear System With Mesh Stiffness Variation

Volume 5: 25th International Conference on Design Theory and Methodology; ASME 2013 Power Transmission and Gearing Conference, 2013
Parameter excited oscillations induced by the varying tooth mesh stiffnesses of the gear pairs cause severe vibration in gear systems. The oscillations become more complex and serious in multi-mesh gear system because more mesh stiffnesses variation occur, which are necessary to be investigated in deeply. To illustrate the complex oscillation phenomena,

A study of spur gear torsional mesh stiffness

International Technology and Innovation Conference 2009 (ITIC 2009), 2009
Through applying finite element methods (FEM),the results of a detailed three-dimensional analysis of the torsional mesh stiffness of spur gears were presented in this paper. Hertz formula can only calculate the contact stress approximately, while FEM can be used to conduct precise analysis of the tooth contact stress and deformation.
