Hey,
i am currently trying to set up multiple energy chains in a small production line setup. My current setup looks roughly like this (chain is running along the Y-Axis):
The design timeline is:
1) Place chain links and join them with revolute motion with angle limits to 0 and 50°
2) Join fixed end rigid
3) Manually pull around the running end to have the running edge upside down
4) Capture positon to make avoid loops in the chain while recalculating
5) Constrain running as a slider with a 108mm offset (Z) of the lower side with limits to both sides (Y)
6) Place Linear Assembly
7) Constrain running end to linear carriage (?)
On this last step I have tried multiple different approaches with joints but they all seem to fail as every joint requires a origin point which already takes away more than one degree of freedom. My last approach was Planar Joint which should only constrain the end of the chain to the XZ plane of the carriage as all other degrees of freedom are already constrained by the chain itself:
Despite initially working, Fusion still marks this planar constrain as yellow and after hitting revert position, it fails to compute.
Coming from Inventor I was used to one of the two workflows for this situation:
1) create running path for chain as 3D sketch and constrain all parts to this path (does not work in fusion as projected geometries are not updated when moved (afaik))
2) same approach as described in fusion but only constrain two planes at the end
EDIT: to make it a little bit more clear: the approach I described works. The issue with the approach is that the design freezes once there are timeline jumps or someone reverts the position.
Has anybody a suitable solution for this design issue?
Best Regards
Malte
