Designing six-bar linkages
Designing six-bar linkages
(OP)
There are all kinds of graphical methods to construct 4 bar linkages. Is there a graphical means to construct a 6 bar linkage? Is it more or less trial and error / experience? How do you know where to place the joints to achieve the movement desired?





RE: Designing six-bar linkages
I'm not sure how a 6-bar linkage works. I'm not even sure if I've ever seen one. I'm familiar with 3-bar (slider-crank) mechanisms and 4-bar linkages, but I would have thought that a 6-bar linkage would be some combination of one or the other or both.
Do you have an example of one in operation?
Engineering is not the science behind building. It is the science behind not building.

here's an interesting applet that the user can change for different patterns....might give some ideas.

here's a website showing different examples of 6-bar linkages

as re the geometry and/or where to place anchors, it depends on what motion(s) you're trying to obtain and may very well be trial and error.
I did some of this kind of linkage design in SolidWorks and it took some (...ok, a lot of) time to get what I wanted.

That Synthetica program looks interesting though. I'll try to download and play with it.
Most interested in designing hinges for doors and covers where conventional single axis hinges won't do (like some kitchen cabinet hinges).
Thanks.
