After the user configures all of the settings, click Plot to draw the Campbell diagram.
•RPM-Frequency: Shows the magnitude value to the RPMs against frequency graph
•RPM-Order: Expresses the frequency using order by converting the RPMs against frequency graph. The following is the formula for the conversion.
•N = Frequency*60/ Ω (N:Order, Ω:RPM)
Figure 2 shows the constant ratio plot that compares RPMs against order after conversion.
