DES recently performed fastener vibration testing per MIL standard, MIL-F-25173A. MIL-F-25173A is a military specification aimed at determining qualification criteria for aircraft fasteners and equipment. In this case, DES focused on the vibration testing of a particular fastener to be used in aircraft applications. Tests were conducted on DES’s Unholtz-Dickie Electrodynamic Shaker. The MIL-F-25173A standard requires specimens to be subject to sinusoidal vibration testing, cycled between 10 and 55 Hz uniformly and with a constant 0.06 inDA displacement. Tests shall span the course of 90 minutes over three perpendicular axes.
