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.

Load analysis with varying mesh stiffness

Computers & Structures, 1999
Abstract The design of proper modification of tooth flanks or mismatch of a pair of gears relies on an accurate computation of the loading and stressing distribution over the gearing surfaces at any phase of mesh. The existing methods, however, are either too simplified or too computationally expensive.

A physically based approach to the accurate simulation of stiff fibers and stiff fiber meshes

Computers & Graphics, 2015
We devise a physically based approach to the accurate simulation of stiff fibers like human hair, wool, or yarn. For that we describe fibers as three-dimensional coupled oscillator networks. The application of special analytical mapping expressions allows us to mimic the existence of Young's and shear modulus in the oscillator network so that real ...

On the Stiffness of the Mesh and Urethral Mobility: A Finite Element Analysis

Journal of Biomechanical Engineering, 2017
Midurethral slings are used to correct urethral hypermobility in female stress urinary incontinence (SUI), defined as the complaint of involuntary urine leakage when the intra-abdominal pressure (IAP) is increased. Structural and thermal features influence their mechanical properties, which may explain postoperative complications, e.g., erosion and ...

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,

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 ...
