As per MIL-STD-883E, Method 2002.3, the shock test is intended to determine the suitability of the devices for use in electronic equipment which may be subjected to moderately severe shocks as a result of suddenly applied forces or abrupt changes in motion produced by rough handling, transportation, or field operation. Shocks of this type may disturb operating characteristics or cause damage similar to that resulting from excessive vibration, particularly if the shock pulses are repetitive. The system employed by Nanomatronix develops the kinetic energy electromagnetically. An iron core “bullet” is attracted to the magnetic core of a solenoid by the dense magnetic field that is created as current flows through the field coil of the shock tower. As the bullet is drawn into the center of the magnetic field the acceleration increases exponentially as the gap reduces to zero on impact causing the high impact shock. The properties of the impacting materials determine the pulse shape and duration. See the standard documentation for more information on test requirements, conditions, and procedures related to your application.
