Strategy: Scaling Results for Centrifugal Loads in a Combined Load Set

The omega term in the force calculation that Creo Simulate uses for centrifugal loads is not linear, due to the following relationship:

F(centrifugal) = mass radius omega 2

You can correct for this by creating a load set that contains only the centrifugal load and rerunning the analysis with this load set. Then, determine the total load resulting from the centrifugal load set. Using this information, you can determine the true scale factor you need to enter to achieve the desired load scaling. To determine the scale factor, apply the following formula:

scale value = (WN/WE)2

Where WN is the acceleration or velocity specified in the load definition and WE is the acceleration or velocity you want to achieve through scaling.
