Maintenance & Technical > KX500 Aluminum Frame Conversion (AFC)
Broken AF frame - Do you know of any?
mxaniac:
That would be correct, it is. I'm simulating a high load on the steering head such as when you overshoot the tabletop and land on the front wheel, not that I would ever do that but you know hypothetically.
Here is a deformation plot, in this model I've boxed in the high stress area with 5 mm plate.
sandblaster:
Very nice.
I guess it's time to up the tube thickness...
mxaniac:
Just to be clear, that last plot is showing exaggerated displacement and not stress.
jBernard:
wonder if putting a strip of alum the width of the rail on the inside of the rails between the Y and the top motor mount to beef it up would help. basically just re-inforce the area showing failure.
i'm doing a front headstay as we speak, glad to see that it may take some of the load off.
mxaniac:
Well for entertainment purposes mind you I modelled up fish plates between the rails and on the side of the rails towards the engine tiening the Y together with the motor mounts and it greatly reduced the stress in that area. Combined with the front head stay and a rigid rear one things are starting to look iffy instead of disasterous.
