MIL-STD-167-2A: Mechanical Vibrations of Shipboard Equipment
Exclusions: It generally does not cover specialized equipment like antennas, weapons systems subject to shock loading (covered by MIL-S-901), or equipment on ships with non-conventional propulsion like water jets. Types of Vibration Covered
MIL-STD-167-2A is a Department of Defense standard specifically covering mechanical vibrations of shipboard equipment, focusing on reciprocating machinery and propulsion systems. It is the companion to the more common MIL-STD-167-1A, which focuses on environmental and internally excited vibrations for general equipment. 🛠️ Core Purpose
The "A" in MIL-STD-167-2A (dated May 1992) represents a major revision. It refined the testing procedures and acceptance criteria used by manufacturers to prove their equipment is "sea-ready." If a piece of equipment passes these tests, it means it can handle the intense, rhythmic pulsing of a ship’s propulsion system for years without a breakdown. How Engineers Use It
