How do you graphically take into account friction in the pins?
the rhino file was made using the plug-in:

Hello everyone

Hello angel,
Could you clarify your question better?
I didn't understand what you mean by

How do you graphically take into account friction in the pins?

Let me understand.
I don't have rhino so the file doesn't open it.
post an image.
Hi.

 

[AngeloB]

I just wanted to figure out how to count friction in the pins in a graphical calculation.

with the plug-in of the ledas you can study the cinematic in 2-3d directly in rhino.
for me, I use autocad lt and rhino, it is a new thing but I think that any cad3d can do the same without problems.

I used vn4d and graphically gave the value of friction force on the pins.
Maybe you mean that?
Hi.

 

[AngeloB]

I calculated the forces between the various parts of the mechanism by graphical means.
but graphically I am not able to take into account the frictions in the pins.
In this case there is no problem, but near the dead points I think it would be better to take into account.

for the graphic calculation of the binding reactions with friction in the pins then see on page 210 "letions of applied mechanics" lava duct or on these Apunti
