HSXX20 Shock Test System

The Challenge

Certain products and components must survive extreme impact events. Consider the case of the fuze attached to penetrating ordinance—the “bunker buster” bomb. In order to provide the intelligence for the munitions, it must survive extreme impacts and continue to function.

To simulate these extreme impact events, Air Force Research Laboratory (AFRL) required a shock system capable of:

• Maximum velocity change up to 150 ft./sec (45 m/sec).
• Maximum acceleration amplitudes up to 25,000 g’s

The Solution

The performance requirements would lead to the fastest vertical shock system that Lansmont has built to date. The HSXX20 Shock Test System utilizes a unique, revolutionary new design feature—the “active” seismic base. The active seismic is attached to a nitrogen‐charged piston and is accelerated upwards towards the falling table during the shock test.

With this additional performance boost, the HSXX20 can generate maximum velocity changes up to 180 ft./sec (54.9 m/sec). This results from the shock table going from 0 to 122 mph in less than 40 feet.
