Hi,
I'm doing a standard planetary gear system analysis (pictured), however when verifying the results I find my planetary gear speed is coming up as 378 deg/sec when by hand calculations it should be 270 deg/sec.
However what I did notice while writing this is that the given answer of 378 deg/sec - 108 deg/sec (the mechanisms calculated arm rotation) = 270 deg/ sec. So I think my measurement is adding the rotation of the arm and the rotation of the planetary gear, otherwise that's a huge coincidence.
For the measurement I have chosen Type->Velocity and for the Motion Axis as one of the rotation axes that the pin joint connects the planetary gear.
So my question is; does anyone know how to measure the local rotational velocity of the planetary gear (assuming that it's not a coincidence)? The answer should be 270 deg/sec
Many Thanks,
Cameron
