The peak acceleration magnitude of the trapezoidal pulse is Am and its duration is TD.
The measured acceleration pulse shall be contained between the brOken line boundaries and the measured velocity change (which may be obtained by integration.of the acceleration pulse) shall be within ten percent of the ideal pulse which approximately equals o.5 Am g (2TD-TR-TF)o ‘integration‘o ‘etermine velocity change shall extend from O .QTD before the Pulse tO O.lTD after the pulse. Rise (TR) and fall (TF) times shall be less than Or equal 0.1TD. ,, FIGURE 516.3-5. lse configuration and iti% 11 ante mlta. M3THOD 516.3 19 July 1983 516.3-10
