How can I use motion study to calculate resultant forces on a follower in a cam setup?
I'm trying to design a cam lobe that will open a bay door with a pole. The pole will move at a constant linear velocity, say 1 inch per second. I want to verify that the force required to do this doesn't exceed a certain amount, say 5 lbs. There will be friction between the cam and the pole, and the cam will be held shut with a spring when not acted on.
Once I get working geometry, I want to simulate the forces and moments to make sure the door can actually physically open:
- I add a downward linear motor to the follower as it will be moving at a constant speed (say, 1 inch per second). The assembly moves as it should, looks nice.
- I then add friction coefficients in the "contacts" button.
- The door will be held closed with a spring, so I add a spring force to the top of the box.
Can't figure out what to do next.
