Does anyone have any experience modeling a circular saw blade?

I am looking at the stress caused by centrifugal force as well as impacts on the saw teeth not to mention the forced vibration resulting.

I suppose I am needing to look at a 3D non linear dynamic response analysis type although I don't think this will include centrifugal forces.

To model the impacts on the teeth as they hit the work, I was considering applying the impact forces to successive teeth and the correct time using the above analysis type. This is a kind-of quasi static approach and I am unsure of its validity.

I am also unsure of whether to account for the fact that I am trying to analyze a dynamic impact situation in a somewhat static way. What I mean here is that if the saw blade has considerable inertia (this one does) then as the impact accurs, part of the force instantly comes from the motor driving torque and part comes from the rotational inertia of the blade.

Any comments are welcome.

Thanks for reading!

I think I will try the first approach.

How would I apply a torsional spring at the inside diameter of the saw blade disk? Do you mean that I should use a beam connected to the disk by rigid links and rely on torsion of the beam?

Do you think that my proposed method of applying successive impacts to the teeth is valid?

Thanks again.
