Testing / Dynamics

Dynamics

Shock, vibration, inclination, acceleration, and pressure simulation — high-impact testing for shipboard and airborne qualification, fully instrumented for shock and acceleration data capture.

Applicable specifications

MIL-S-901 MIL-STD-167 MIL-STD-202 MIL-STD-781 MIL-STD-810 MIL-STD-331 MIL-E-4158 MIL-E-5272 DOD-1399

Shock

High-impact shock

High-impact testers simulate underwater detonations and shipboard gunfire for test items and fixtures up to 7,400 lb, verifying that shipboard installations withstand the shock loadings of nuclear or conventional weapons.
