Pyroshock Attenuation Tool

Estimate SRS attenuation with distance for point source pyroshock using the MIL-STD-810G RLDS method.

Input Parameters

Point Source (RLDS Method)

Explosive bolts, separation nuts, pin pullers, bolt cutters

Source SRSUse Custom

Peak G (plateau)

Knee Frequency (Hz)

Reference Distance D₁ (m)

Distance where source SRS was measured

New Distance D₂ (m)

Distance to predict SRS (ΔD = 0.85 m)

Number of Joints in Path

40% reduction per joint (max 3 counted)

SRS Attenuation Results

Point source (RLDS): D₁ = 0.15 m → D₂ = 1 m
