Miles’ Equation: Equivalent Acceleration for Random Vibrations

Miles’ equation was originally developed by John W. Miles in 1954 to assist him in modeling the structural fatigue of aircraft using only one degree of freedom. The general form of the equation is: where GRMS is the root mean square acceleration, measured in G’s, fn is the natural frequency, Q is the amplification factor …
