Modeling Wire Rope and Sheave

Modeling Wire Rope and Sheave

Modeling Wire Rope and Sheave

(OP)
Is it possible to model the movement of a wire rope over a sheave. If not any ideas how to "fake it"


RE: Modeling Wire Rope and Sheave

Have you looked at Animator? What version do you have?

The problem is having the wire rope, which i have modeled as a part, dynamically move over the sheave. SW 05

RE: Modeling Wire Rope and Sheave

I've done it with configurations, start point/end point.  I've never been able to model a dynamic wire/roller model.

RE: Modeling Wire Rope and Sheave

(OP)
Thanks for all your advice, but i have found a way to make this work. Not sure my pea brain totally understands it, but it works

RE: Modeling Wire Rope and Sheave

What is your solution?

RE: Modeling Wire Rope and Sheave

(OP)
Hope this make sense, but my situation was a cylinder with a sheave mounted on the end and a rope going over it. I started with my cylinder assembly with limit mates for my stroke. I then inserted a new part and sketched in my centerline for the rope. Mated the fixed end to my anchor, made the sheave and rope end concentric and then put a arbritary dimension in from the anchor pt to the other end of the rope. Then used the equation editor and made the arbritary dimension equal to my limit mate. The only thing with this is that you have to hit refresh after you move the cylinder to the position you want. Still looking for a better way!!!

RE: Modeling Wire Rope and Sheave

I just tried this with limit-mate, so this should help you a little.  I made the min angle 1, and the max angle 359.  Find the limit angle in the tree, probably "D1@LimitAngle1" and double-click it.  Pick the dimension on the screen, and choose equations.  For the equation, copy the limit-mate, and paste it after the equal sign, and then enter "+5" (without quotes).  Your equation should look very similar to this:

CODE

  "D1@LimitAngle1" = "D1@LimitAngle1"+5
Now it will rotate 5 degrees after every rebuild.  
You might be able to cut a part of code from "Ship in a Bottle" to rebuild "x" amount of times automatically.
