After an analysis in RecurDyn is completed, you might want to check the rotation speed of body as RPM. But it is shown as Rad/s in the plot in RecurDyn.
In this case, here’s how to convert Rad/s to RPM.
There are two ways to convert to RPM in RecurDyn.
- Conversion using Math function of Plot
- Conversion using formula in Expression
[Conversion using Plot]
1. After finishing the analysis, click [Tool tab> Analysis group> Math icon] in Plot.
2. Change the Math Type to ‘Scale : alpha * F1' and select the Source Curve1 (F1) as desired curve.
3. Change the Y Scale Factor Type of the Scale Option to ‘rad/s->RPM’.
4. Click ‘Execute’.
[Conversion using Expression]
1. Apply WX(), WZ(), and WY() functions to convert to RPM in Expression.
- [Example] (WZ (Body1.CM, Ground.InertiaMarker) * 60) / (2*PI)
2. Add the Expression created in step 1 following SubEntity tab> Expression group> Request and then click ‘OK’.
3. After completing the analysis, go to the Plot and double-click the Request created in step 2 in the Plot Database to check the graph.
