Basic definition

 

Acceleration of gravity

the accelerated velocity in the surface of earth caused by gravity.

Pulse duration

Shock pulse rises from the reference value to the maximun value, the time it taks to decrease to the reference value.

Severity of shock test

It's the combination of peak acceleration and nominal pulse duration.

Velocity variation

The absolute value of sudden velocity variation caused by the implementation of specified acceleration.

Basic pulse waveform

 

a. Half-sine pulse: Ideal pulse with the time course curve which is half period of half-sine wave.

b. Postpeak sawtooth pulse: Ideal shock pulse with the time course curve which has asymmetric triangle with short falling time.

c. Trapezoidal pulse: Time course curve is the symmetric quadrangle with short rising and falling time.
