Hello
I am modelling the process of coiling a spring. This problem was solved by fixed one end of the rod and winding it on the cylinder by the other end. But that doesn't sound like a real process. It is necessary to rotate the cylinder, as it is done in hot coiling of springs. Several problems arose with this: I could only rotate 90 degrees full construction via Rotating Domain in Deformed Geometry if the rod is a bit cut into the cylinder. (I try to rotate using different modules (Rotating Frame in Solid Mechanics, Rotating Domain in Deformed Geometry, described the rotation through Multibody Dynamics), but it didn't work). But if I can rotate the construction, the rod does not contact an object that it should hook on to start coiling. The contact pairs and interactions are defined. Could you please advise how to model this process more correctly? Thanks |
