Animating a Normal Modes Analysis

In this section, you animate the model to inspect and relate mode numbers with mode shapes. Remember, doing a normal modes animation outside of Adams Vibration is called a frequency-domain animation. So, if you’re referring to the Adams PostProcessor online help for more information on normal modes animation, read the sections on frequency-domain animations.

To view a normal modes animation:

1. Create a new page by selecting the New Page tool

2. Right-click the Page Layout tool

, and select the 1 View tool

3. Set the pull-down menu located in the menu bar below the File menu, to Animation.

Adams PostProcessor switches to animation mode.

4. Right-click the animation window, and then select Load Vibration Animation.

The vertical animation appears in the animation window.

Note:

The label on the animation is EIGEN_#, where # is the run number of the animation.

5. Select Normal Mode Animation.

6. Close the Information window.

7. Next to the Mode Number text box, use the

tool to change modes.

8. Select the Play tool.

9. Study the mode shapes for modes 9 and 15.

These appear to have the greatest effect on the vertical motion. Other modes affect the lateral motion and we’ll discuss them later.

If you see excessive movement for a given mode, you can automatically rescale it by entering 0.0 in the Scale Factor text box, or adjusting the scale with the

tool.

Note:

To view the animation from different angles, rotate the view by typing a lowercase r and then using the mouse to rotate the view.
