How do you create a welded link chain?

What constraints should be placed on the links to have an assembly that can follow a given trajectory while remaining flexible?

 

Be careful, when I talk about chain, I shouldn't understand bike chain, but this one

Have you seen this question?

I think what answer to your question.

Hello

 

You can start by putting the links back together.

Hello

It must be fesable by creating for each link 1 axis on each end that will correspond to the possible rotations, then assemble each link together by pivot

 

But hey, it's laborious...

Hello

 

By default I would say insert a link, then a tangiance constraint between the sirface with the 2nd, then the copy function with the constraints, but this type of constraint is always a bit random!

@Lucas: from what I understand he would like the channel to move! So we shouldn't put standard constraints.

Is it possible on Solidworks to create a guide curve composed of small segments of equal length (distance from the center of a link)? This curve remains flexible and allows you to follow a trajectory.

 

All that remains is to assemble the link in each segment.

Thus, with a variation in the trajectory of the curve, the links will follow.

Hello

 

I understand the problem, I have the same problem... with this channel

Have you seen these tutorials

http://www.lynkoa.com/tutorial/directory/cable%20et%20corde?&price=all

 

It must be a good lead

 

1- with an assembly and containment of cam it should be able to do it too

The problem is the number of constraints and your PC will work like crazy

 

2- You can also create a straight segment on the axis of each link

length of the segment the radii of  the inner fibers

that you reread by the end points

 

that you can hide and leave only the links that appear

Hello

I'll see, if you recreate the links, the use of constraints with a spline of the assembly.

Here again, it's a lead like any other!

Kind regards

The constraints, you have to create a trajectory on which your links will go, put a fixed point on your link, then with the 2 make a trajectory constraint, in advanced constraints and then you need a parallel constraint between a surface of the link and a plane.

Hi @ pmartinez2

 

here is a welded link chain made under SW 2012

 

It is an assembly and all the links are movable between them

via a connection point on the ends of the segments the segments can be hidden
