Gear tooth mesh stiffness: A comparison of calculation approaches

Mechanism and Machine Theory, 2016
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 ...

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 ...

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.
