Shock Machine Capability
TDS-15

Shock Machine capability is rated in terms of VELOCITY. The formula for calculating the velocity change for a half-sine pulse is:

    386 x .64 x g x t = V where

    V = Velocity Change (in/sec)
    g = acceleration (g)
    t - time (seconds)

For a shock machine whose velocity change is 200 in/sec, the calculation for maximum g is as follows:

    0.5 ms: 200 = 386 x .64 x g x .0005
    Maximum g level at 0.5 ms = 1600 g

    6 ms: 200 = 386 x .64 x g x .006
    Maximum g level at 6 ms = 130 g

    18 ms: 200 = 386 x .64 x g x .018
    Maximum g level at 18 ms = 45 g

For a shock machine whose velocity change is 300 in/sec, the calculation for maximum g is as follows:

    0.5 ms: 300 = 386 x .64 x g x .0005
    Maximum g level at 0.5 ms = 2400 g

    6 ms: 300 = 386 x .64 x g x .006
    Maximum g level at 6 ms = 200 g

    18 ms: 300 = 386 x .64 x g x .018
    Maximum g level at 18 ms = 65 g
