## What Does Double Amplitude (DA) Mean in Sine NASA

What Does Double Amplitude (DA) Mean in Sine Vibration? When you input your frequency and acceleration data into a sine vibration frequency response NASTRAN deck, you may run into that cryptic notation, 032 inch DA from 1020Hz This is what is known as a vibrational amplitude But since NASTRAN does not know what DA is, and you probably don't either, you need to convert that value

## Double Amplitude Displacement Vibration

Double amplitude displacement is the total deflection in both directions The period of vibration is the time it takes for the mass to move from its equilibrium position to its peak in one direction to its peak in the other and back to its equilibrium position READ MORE Theory Of Vibration Simple Harmonic Motion As a result the weight W oscillates about OO undamped The maximum displacement

## Displacement Amplitude an overview | ScienceDirect Topics

The displacement amplitude at the loaded point along the force direction is obtained by three different methods so the peaktopeak amplitude (also known as double amplitude) is 2X It appears to be an accepted convention to express displacements as double amplitudes, but velocities and accelerations as singlepeak amplitudes, so some care is needed, especially when interpreting vibration
