dynamic simulation

normandajc — Tue, 13 Dec 2022 15:32:49 GMT

I would like to create a force for example of 1N which is exerted on the body "axeBras". This force rotates and is centered in relation to the center of the "Plateau" body. (see force.pdf)
I can't create this force. I can make my pieces move by moving the tray for example.
I don't know how to do it. I join my assembly
If someone can solve the problem and send me the solution.

Your assembly has redundant joints and is missing two Rolling Cylinder on Cylinder Joints?

Change to...

Now the joints are not redundant.

Thank you very much. your help is great

Those tips were just to get you closer to the solution - did you figure it out?

Hello,

I created an axis and a point to be able to realize a constraint and remove the redundant constraint.
I didn't succeed, but you did. I must make a mistake.

I did not create any geometry.

For the Mate I selected side if cylinder feature (Inventor selects the virtual axis of the cylinder) and the circular edge of hole (Inventor selects the virtual center point of the circle).

For the Rolling Cylinder on Cylinder Joints turn on the visibility of the pitch diameter surface bodies in the gears.

Post back if you still can’t figure it out.
