Dynamics Problem with flexible cable
Dynamics Problem with flexible cable
(OP)
I work for a company that manufactures a mechanical cable conveyor. The system works by moving a cable with discs attached through a stainless steel tube.
I am trying to determine the total pull on the system and I'm having some issues with the physics of the elbows. The cable is pulled through a large radius elbow (48in CLR). I'm trying to find the force required to do so. Due to the fact that the discs not the cable rides on the ID of the elbow it makes the standard belt/ pulley equations useless. I know I need something that takes into effect the contact surface area and that the cable is attempting to be pulled straight so it doesn't follow the ID of the tube the entire time. Please help.

I don't have a reference for these equations handy, but they shouldn't be hard to find.

Mechanical engineering handbooks such as Kent espacially older volumes, dating bak to the '40's have good detailed analysis on conveyors not exactly of the type that you have but at least it should get you in the right direction
