Modify Body - Velocity Initial Conditions
You can specify initial velocities for parts. Adams View uses the initial velocity during the Initial conditions simulation, which it runs before it runs a Simulation of your model.
You can specify translational and angular velocities for rigid bodies and only translational velocity for point masses.
■Translational velocity defines the time rate of change of a part’s center of mass with respect to ground or another marker in your model. You can specify translational velocity for each vector component of the marker.
■Angular velocity defines the time rate of change of a part’s rotational position with respect to the CM marker of the part or another marker in your model. You can specify angular velocity for each vector component of the marker.
If you specify initial velocities, Adams View uses them as the initial velocity of the part during assemble model operations, regardless of any other forces acting on the part. You can also leave some or all of the velocities unset. Leaving a velocity unset lets Adams View calculate the velocity of the part during an assemble operation depending on the other forces and constraints acting on the part. Note that it is not the same as setting the initial velocity to zero. Setting an initial velocity to zero means that the part will not be moving in the specified direction when the simulation starts, regardless of any forces and constraints acting upon it.

Tips on Entering Object Names in Text Boxes. Translational Velocity | |
Ground | Select to specify the global reference coordinate system as the system in which the translational velocity vector components will be specified. |
Marker | Select and enter a marker along whose axes the translational velocity vector components will be specified. |
X Axis/Y Axis/Z Axis | Select the axes in which you want to define velocity and enter the velocity in the text box that appears next to the axes check boxes. Remember, leaving a velocity unset lets Adams View calculate the velocity of the part during an initial conditions simulation, depending on the other forces and constraints acting on the part. It is not the same as setting the initial velocity to zero. |
