    Hi Monu,

    I am assuming you have a assembled model. 

    You can apply rotational motion(displacement) to revolute joints. Use Apply motion option and create a displacement on Revolute joint.

    @Monu,

     

    Within the motion panel you can enter the value of motion.

    Hello sir,

    I have to apply velocity as 50 rpm, so in property have to select velocity or displacement

    and 

    in value, if I will enter 50 then will it take in rpm automatically.

    Hi Monu,

     

    sorry In my earlier post I posted as displacement. Use velocity in the same motion panel. The value furnished will be treated as velocity.

    and what will be the initial condition in this case

    In MotionView you define units and I am not sure what unit system you are following. You can find the unit system in Model Browser>> Misc>> Units. If the units are in seconds, you need to convert the RPM from RPS

     

    Please check and update accordingly.

    This is not MotionSolve parameter. It is from RADIOSS engine. Please check.
