Rotation modelling

Hi! I wanna model the rotation of a gear (wheel) with a preload in the pinion. I asume the preload is modeled with a moment but, how do I model the rotation? And which analysis type should I choose? (I don't want  a quasi-static one). Some analysis don't let me include a LOAD. Thanks in advance!

    As Static analysis, you have to fix your gear in rotation. When the gear is fixed on rotation, you can apply the load.

    Thanks! But how do I create the motion of the wheel  rotating? Would that be a transient analysis?

    Please refer below example from OptiStruct example guide.But that is solved using quasi static analysis.

    OS-E: 0115 Finite Sliding Contact

     

    What is output/end objective of your model?

    You can also do multibody simulation using Altair MortionSolve.

    The goal is to measure the transmission error. I already did (some months ago) a quasi-static analysis. Now I want to do it transient, dynamic so I have to change the way I apply the rotation. (In the quasi-static I did it using SPC).
