Rotating a Component About an Axis

Good Afternoon,

I am trying to create an animation of the following assembly that moves in various degrees of freedom. So far i have been able to rotate the 1.5" pipe inside the 2" sleeve and also slide the 1.5" pipe within the 2" sleeve. However, i am stuck on rotating the 2" sleeve and the components associated with it like a see saw about the small 0.75" "pins". I tried using a "motor" function but that does' seem to work, or atleast i have chosen the wrong parameters. The last move i need the model to make is rotating the 3" sleeve and the rest of the components that rest on top of the 3" sleeve around the 2.5" sleeve

Any help or tips would be greatly appreciated.

Thanks,

Craig

Correct Answer

Check this if this helps. Have done something quick so haven't checked everything. The only thing you need to do (after adjusting the motors, etc.), instead of animation use basic animation.

You need to redefine your mates in order to get that. I'll try to make something but where you would need the seesaw action??

About the 0.75" Pins. The 0.75" pins will be welded to the 2" sleeve and rotate inside the supports on each side of the 2" sleeve.

Thanks!

Haven't checked the files out, what does basic motion do for you over animation for this problem?

Jared when I use animation, the angle mate doesn't work (not sure why as I didn't had the time to check that) but with basic animation that worked along with the motor.

Deepak,

I was able to add the motion of the 1.5" pipe being able to telescope back and forth. However, when i tried allowing the top portion of the assembly that is attached to the 3" pipe, rotate around the 2.5" pipe, i couldn't get that to work. As you can see i tried adding a motor, but it doesn't seem to work. Is it possible that the symmetry constraint between the two faces of the support and the right plane of the assembly causing it not to move? Thanks again for the help earlier.

Thanks,

Craig

does removing it fix the problem? ( the symmetry mate)

Actions

Craig Jameson @ Jared Conway on Jun 4, 2014 8:28 AM

No, i tried removing that particular constraint and the supports move too much in the model and the basic motion will not calculate a solution. I also tried changing the constraint from the right plane of the entire assembly to the right plane of the 3" pipe that the supports are connected too, and that yielded the same results. The other method i tried was making the entire top half into a sub-assembly. I was then able to rotate the top portion around the 2.5" base leg like i needed, but the sub-assembly locked all the other moving parts that Deepak helped me with.

not clear on what the status of the issue is

if basic motion won't solve, it may be that you need solidworks motion

but it also sounds like you have problems with mates and components. unless the assy will drag into the motion you want, motion or animation won't work either. note that some mates are not supported by solidworks motion

Check this one. I had suppressed some mates and added other one to make it simpler. But again not understanding as why motion is not working but basic motion work. Might be because of motors along with angle and distance mates.
