Creating Vibration Volumes

You can calculate a dynamic envelope or volume of parts. The envelope is defined by using the positions in the form of coordinates in the ASCII (American Standard Code for Information Interchange) Positions file.

Before you begin:
  1. From the top bar, select Add > Content.
    The New Content dialog box appears.
  2. In the Physical product Structure category, click VOCVibrationVolume .
    The Vibration Volume dialog box appears.
  3. In the Selection box, select the required parts.

    The selected parts are taken into consideration for generating the vibration envelope or volume.



  4. In the Reference product box, select the product with reference to which the displacements of the selected parts is computed.

    Note: By default, the root product is selected as the reference product.

  5. Select the File option and do any of the following:
    • Enter the complete path of the positions file in the box.
    • Click Browse to select the positions file.

    Note: The supported file formats are VDA (.vda), ADAMS (.txt), and .mvf.

  6. In the Accuracy box, enter the accuracy value.

    The accuracy value is nothing but the grain size of the mesh. Lower the value of the accuracy, finer is the meshing and accurate is the result.

  7. Select the Enable Simplification check box and enter the simplification accuracy value in the Accuracy box.
  8. Optional: For improved performance, under Envelope, select the Simple option.
    The results are computed using V5 algorithm.
    Note: If the simple envelope type is selected, the quality of the result may be impacted.
  9. Click OK.
    The vibration volume is computed and displayed as a 3D shape in a new window.
