This Military Standard provides instru

6、ctions for the selection, instal-lation, maintenance, and repair of vibration damping materials.2. Noise radiated from a ship into the sea is in part due to the resonanceresponse of the ships structures to applied vibratory forces. These forces,for the most part, originate in machinery or equipment

7、supported on foundations,bulkheads, and decks. The turbulent flow of water around the hull of a surfaceship or submarine produces hydrodynamic forces which excite the hull plates invibratory motion. Damping treatments applied on these structures reduce theamplitudes of motion and force at their nume

8、rous resonance frequencies, and thusreduce radiated noise.iiiProvided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-MIL-STD-2148(SH)12 August 1983CONTENTSPageParagraph 1.1.11.22.2.12.23.3.13.23.33.43.53.63.73.83.93.103.113.123.133.143.153.163.173.184.4.14.24.
