I’m trying to carry out a static analysis of this pulley blocks internal mechanism.
The ring end would hang from a shackle, the shackle (essentially another ring) which might be of several different sizes but being circular in profile would point load the ring somewhere around its internal face. The main weight of the load would be taken on the central pin, (with the square end) as this pin would have a circular sheave around it into which the rope would sit. That rope would go through an identical pulley at a distance from this one and then return where it would be ‘made off’ or tied to the smaller pin at the opposite end of this binding. Due to the mechanical advantage through the mechanism this second pin would be subject to half the loading of the middle pin and the top ring I believe.
I don’t know how to set up this simulation due to the curved face of the ring, the face that the loads would be applied through the two pins which are part of this model in different weights. I also would like to custom load some material specifications as the main body would be silicon bronze and the two pins phosphor bronze.
Any help getting me closer to my goal would be gratefully received!
