WebWhen you input your frequency and acceleration data into a sine vibration frequency response NASTRAN deck, you may run into that cryptic notation, 0.32 inch D.A. from 10-20Hz. This is what is known as a vibrational amplitude. But since NASTRAN does not know what D.A. is, and you probably don't either, you need to convert that value into ... WebSine Damage The sine fatigue damage is expressed as follows: sine damage = (Gin Q) b (Gout ) b (6) where Gin and Gout are each in terms of a peak G level Q is the amplification factor (typically Q=10) Equation (6) assumes that the sine amplitude is at its peak level extremes 100% of the time. This assumption is reasonably accurate. caleb sima net worth
