M/RAD's pneumatic shock machine is available in three table sizes (9, 16 and 24 inches square). Table extenders may be provided to increase table size. These machines will produce a shock pulse in the vertical direction using compressed air to force the carriage to impact on the shock machine base. Elastomer pads are used between the carriage and the base in the impact area to produce half-sine pulses, lead pellets for sawtooth pulses and pneumatic cylinders for square pulses.

The design of the programmers affect the time duration of the pulse while the air pressure and drop height are used to accelerate the carriage to determine the magnitude of the shock pulse. The basic structure of the machine is a heavy steel weldment filled with reinforced concrete which will not deteriorate under repeated shocks. The structure contains sufficient mass so that no additional ballast will be required. The structure is supported on four passive air springs with dampers to isolate the shock from the floor. The test item is mounted to a solid carriage with heavy duty steel inserts in the top surface. The carriage is supported and guided by the lifting and driving piston rod. Friction brakes are used as a rebound brake and as a quick release device. A microprocessor control is available to provide a single point for shock machine set up. The controls for the machine are mounted in a control panel on the front of the machine. All regulators, gauges, signal lights, relays and push buttons are located here.
