Spiral bevel gear analysis
Spiral bevel gear analysis
(OP)
Hello,
I am trying to do an analysis on a pair of spiral bevel gears on Creo Simulate 2.
I want to check 1)Root bending stress and 2)Surface contact stress.
The gear is rigid,and the pinion is free to move on Theta.
The problem is that it takes too long to finish an analysis and the results are not what I am expecting.
It's hard to get a convergence under 10%, and as I refine the mesh,days were added to calculation time.
The system I am running Simulate is a 12core @ 3.5Ghz CPU and 32GB Ram. I set Simulate to use 16GB of the Ram.
I am asking if anyone has get involved with Gear analysis on Creo Simulate to give me some advice or tips if there any.
Thanks in advance.

RE: Spiral bevel gear analysis
What is applying the torque load? Can you put your model?

Also, assigning 16Gb of solver RAM sounds way too high. Unless the model is enormous (millions of equations/DOF) then you won't need that much. There are notes on what memory is required for a given analysis in the log file, but just try reducing it for starters. A machine with that your spec is capable of solving huge simulations, so a simple gear tooth should not make it even blink.

It is my understanding they are not the same. Gear contact stresses and limits are empirical quantities.
My advise is to use gear analysis software and skip FEA.
