Gear Stress Convergence
I'm working on the interaction between two gears to determinate the von Mises stresses on them. In order to make the simulation smaller I'm only dealing with a small piece of each gear, as picture below.
The contact surfaces on the teeth have been prescribed as frictional with a 0.1 value.
I'm using Revolute Joints to ground both gears, and in one of them I'm applying a 116 Nm torque and on the other one a rotation with zero value.
The standard element size is 3.8 mm, and I have parametrized the face sizing of the engaging teeth as input and the maximum stress on each gear as output.
And the maximum stresses location, with the results of a 2 mm face sizing.
This is the result so far, x axis is the element size (mm) and y axis is the stress (MPa). Gear 1 is the one with zero rotation, and gear 2 is the one with applied torque.
Any tips on getting the stress to converge?
