F = force D = peak to peak displacement g /Hz = acceleration density m = mass f = bandwidth in Hertz f = frequency in Hertz (Hz). a = acceleration V = velocity g = the acceleration of gravity grms = the rms value of acceleration in units of gravity Vibration Equations Sinusoidal Vibration Velocity, Acceleration and Displacement Relationships English Metric V = fD V = fD. V = X g f D = inches peak to peak V = X g f D = meters peak to peak 2 2. g = f D V = inches per second g = f D V = meters per second g = f = frequency in Hertz (Hz) g = Vf f = frequency in Hertz (Hz). 2 2 2 2. a = g = inches/second a = g = meters/second 2 2.
