Abstract:
A method of determining adjustments to decrease vibrations caused by rotating blades, comprising:receiving a plurality of vibration values corresponding to vibrations caused by the blades; providing coefficient of vibration data that corresponds to effects on vibration caused by adjustments to the blades, wherein the adjustments include at least two different types of adjustments having different units of measure; applying the coefficient of vibration data to the vibration values; solving for possible values for the adjustments that may be applied to the blades, wherein the possible values for the adjustments results in the vibrations being less than a predetermined value; determining a total normalized adjustment value for each of a plurality of sets of adjustments, wherein at least one of the sets has more than one type of adjustment, the total normalized adjustment value corresponding to values of adjustments normalized by each type; and selecting a set of adjustments having a total normalized adjustment value less than other total normalized adjustment values.
