Springs, belts?

[SWDADA]

how can I add springs and belts in an assembly? I would like them to behave the way they would in the real world, ie; I do not want them to remain rigid for example, the spring should expand and contract when constrained on one side and a force applied on the other

Look into flexible components for springs.

I'll have to think a little bit on what you could do for
belts.

If its a chain you could assemble the chain links as a
slot followers on a curve and it would run like the
"real" world.

Well chains and belts do the same thing fundamentally but when you analyze a comples system requiring work in to details the differences between xhains and belts become important

 

[csusie]

How do you plan to utilize the "real" belt. Mechanism
design? dynamics? accurate drawing views? Dynamic
dragability? Regeneration updating only?

Try to clarify your reasonings and a path to the
solution will be more evident.

If you need the belt to adapt to the pulley diameter, you can define it with a perimeter dimension.
I did this for geting automatically the required axis distance, but never tried to assamble them flexible with the pulley diameter as measurement.
