Modify Body - Position Initial Conditions
In addition to specifying initial velocities, you can also control the initial position for a part’s location and orientation. You should specify the initial position when you do not want Adams View to reposition the part. Adams Solver uses the initial position during an Initial conditions simulation, which it runs before it runs a Simulation of your model.
You can control initial locations and orientations for rigid bodies and flexible bodies but only initial locations for Point masses.
■Location fixes any of the current translational coordinates (x, y, or z) of the part as the initial location.
■Orientation fixes any of the current body-fixed 313 rotational coordinates (psi, theta, or phi angles) as the initial orientation. These rotation angles are those associated with a body-fixed 313 rotation sequence regardless of which sequence you set as the default for the modeling database. (Learn about Rotation Sequences.)
If Adams Solver has to alter part positions to obtain consistent initial conditions during an initial conditions simulation, it does not vary the coordinates you specify, unless it must vary them to satisfy the initial conditions you specify for a joint or a motion.
If you fix the initial positions of too many parts, the initial conditions simulation can fail. Use initial positions sparingly.
For the option: | Do the following: |
|---|---|
Positions held FIXED during assembly | |
Global X, Global Y,Global Z | Select the coordinates that you want fixed during initial conditions simulation. |
Orientations held FIXED during assembly | |
PSI Orientation,THETA Orientation,PHI Orientation | Select the angles that you want fixed during initial conditions simulation. |
 | Add any comments about the part to help you manage and identify it. Learn about Comments. |
