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 ...

Study on Nonlinear Meshing Stiffness of Spline

2015
In the study on the dynamic characteristics of spline rotor system, the spline stiffness is simplified as the constant related with single tooth stiffness. Based on spline single tooth stiffness calculation, according to spline deformation, stress and torque, spline transverse meshing stiffness model is established, and the numerical simulation ...

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,

Calculation Model of Gear Meshing Stiffness Using FEM

International Review on Modelling and Simulations (IREMOS), 2015
This paper deals with gear meshing stiffness as an important input parameter for modeling the gear dynamic behavior. Several calculation models of this parameter exist in the literature and one of the best models is the comprehensive analysis (ranked level A by ISO-6336 standards) which includes all influences, this model can be performed either by ...

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.

Analytical load sharing and mesh stiffness model for spur/helical and internal/external gears – Towards constant mesh stiffness gear design

Mechanism and Machine Theory, 2017
Abstract In previous works the authors presented two load distribution models for gears. One of the models was based on the rigid tooth assumption and the more complex of the two took advantage of influence coefficients obtained from a FEM model to find the load distribution.

Influences of friction and mesh misalignment on time-varying mesh stiffness of helical gears

Journal of Mechanical Science and Technology, 2017
As one of the most important excitation sources of vibration, time-varying mesh stiffness of helical gear pairs need accurately calculated. Compared with spur gears, friction in helical gears is significant. This work for the first time presents an improved calculation method for the mesh stiffness of helical gears with effect of friction incorporated.

A Comparison of Gear Mesh Stiffness Modeling Strategies

2011
Gearboxes are prone to numerous faults that require vibration health monitoring to ensure proper operation. Monitoring methods typically employ casing mounted accelerometers. This data is difficult to interpret because of the many gear mesh frequencies present and is further complicated by the presence of significant amounts of noise. Several different
