Datasheet
All three AVEX Shock Machines are firmware-controlled, pneumaticallypowered shock testers for accurate, repeatable laboratory and production impact testing of specimens up to 1000 pounds, depending on the model. With appropriate pulse generators, a Shock Machine will produce half sine, sawtooth, and square wave pulse shapes which meet exacting military and industrial specifications, or individual test requirements. Generated waveforms comply with typical military specifications, including MIL-STD-202, MIL-STD-750, MILSTD-810 and MIL-STD-883.

When this pressure is reached, the holding brake is released. The carriage is then driven downward by the charge pressure, impacting on a pulse generator mounted on the anvil. Upon impact, the brake is actuated, holding the carriage in a rebound position and preventing secondary impact. Simultaneously a data capture system may be triggered for recording the shock pulse.

The base assembly functions as an inertial mass and reacts with the falling carriage to generate a shock pulse. The assembly is made of high-strength reinforced concrete, encased in a steel jacket, and is supported on four air mounts. It supports a carriage and guide rod, and contains a pneumatic cylinder assembly, an electronic- pneumatic control system, and a control panel. The machine is shipped completely assembled.
