I would like to calculate the force that a extension spring makes to a tube when is wrapped on it. Imagine a circular tube where you wrap a extension spring so it remains tensed up, pressing the tube surface like a clamp.
So I would like to calculate the force (knowing the K of the spring) that the spring makes on the tube walls.
Actually the tube is not circular but has a obround (two flats joined by semicircles) secction, so in the "flat" zones of the obround the spring does not make any clampling (radial) force. So I would like to study different tube sections in order to optimize it.
Could someone help me to simulate this?
Thanks in advance!
