Dear All,

how to apply rotational velocity to any component 

and if possible please revert with loading conditions necessary for below analysis.

    Hi,

    You can try creating an imposed displacement load for this case and choose the relevant rotation axis (XX,YY or ZZ). Create a rigid for the inner ring and impose this load on to the master node.

    Dear George,

     

    Thanks for supporting every time.

     

    I have one query about assigning angular velocity to shaft. my shaft speed is 4500 rpm.

    4500RPM=75RPS=471 rad/sec

    Time required to complete one rotation= 0.01333 sec

    1Revolution=360 degree=6.28 rad

     

    If i want to complete 3 rotations

    Time required = 0.01333x3=0.04 sec

    Shaft need to complete 3 rotations in 0.04 sec.

    3 rotations = 6.28x3= 18.84 radians.

     

     

    X                      Y

    0                      0

    0.04               18.84

     

     

    Is this conditions of curve is right?

    If yes, then i have done one simulation using same conditions but shaft is rotation by small portion only. Not even half rotation.

    Attached is the animation file of above curve.

     

    Please do the needful.

     

    Thanks,

    Hi @Ganesh Munge

     

    Isn't that curve linearly increases velocity?

     

    If your shaft speeds start at time zero, try 0, 18.84 and 0.04, 18.84
