Spring fingers, can this be done
Spring fingers, can this be done
(OP)
I am trying to determine if it's possible to turn over a 20 lbf, 8 inch high cylinder laying on its side using a round tubular section of spring steel slipped over the cylinder and mounted to its base. The spring steel tube would have machined "fingers" that, when released, would curve away from the cylinder (relieving its residual stress) into a semicircular shape. By doing this, some of the "fingers" would push against the ground causing the cylinder to sit up on its base. Once the cylinder is sitting on its base, the "fingers" could aid in stabilizing it. I imagine there would be at least 10 "fingers".
I have a simple model of this, but I am not sure how to attach it here.
I have seen this done with small, lightweight cylinders. My question is, how would I calculate the righting moment available from the "fingers" making contact with the ground. I know the righting moment required.
Thank you for any light you can shed on this problem.
