Recording an Excitation

Kinematics Excitation Recorder allows you to simulate a mechanism without defining complex formulas.


Before you begin: Open a kinematics simulation referencing a mechanism in the Mechanical Systems Experience app. app.
  1. Select either the automatic or the manual mode.

    Tip: Select the automatic mode if your mechanism is under-constrained or if it involves interdependent commands.

    Important: You can lock and unlock commands for partially defined mechanisms.

  2. To modify and record the values of a recorded excitation:
    • In manual mode, use the sliders or spinners in the Excitation Recorder dialog box, and click .
    • In automatic mode, use the sliders or spinners in the Excitation Recorder dialog box in sequence. Any new command value is automatically recorded.

    After a command value is recorded, the Simulation Player goes to the next time step. The time step increment depends on the Time step value you defined in the scenario parameters. Any probe included in the kinematics scenario is dynamically updated.

  3. Repeat step 3 to complete the recorded excitation.
  4. Optional: Use the Simulation Player to animate the command values you have recorded.
  5. Click OK.
  6. To manually modify the values of a recorded excitation:
    1. Right-click the recorded excitation in the tree, and select Edit Table.
    2. To modify a time value or a command value, click the appropriate line in the table and enter the new value.
    3. To add a row, right-click a line in the table and select Add Row.
    4. To remove a line or a selection of lines, right-click the line or lines, and select Delete Rows.
    5. To remove all the lines of the table, right-click, and select Delete All Rows.
  7. To export a recorded excitation to a spreadsheet file, in the tree, right-click a recorded excitation under the scenario and select Export.
