MIL-STD-167-2A: Mechanical Vibrations of Shipboard Equipment

• MIL-STD-167-1: Mechanical vibrations (general, for all shipboard equipment – canceled/superseded by -2A for most naval applications).
• MIL-STD-167-2A: Specifically for Naval Sea Systems Command (NAVSEA) equipment.

Applications

• Displacement: The amplitude of vibration (in inches or millimeters).
• Velocity: The rate of change of displacement (in inches per second or millimeters per second).
• Acceleration: The rate of change of velocity (in g's or meters per second squared).

Purpose: It defines vibration test requirements for equipment installed on U.S. Navy ships (and some other marine vessels) to ensure it can withstand:

A very specific request!

MIL-STD-167-2A outlines the requirements for mechanical vibrations in shipboard equipment, specifically focusing on type II-environmental vibration, to ensure durability under operational conditions. The standard details testing procedures for detecting, designing, and validating equipment against structural failure caused by vibrations during service [1,2].
