NICOP - Optimized Design for Active Noise and Vibration Control in Marine Platforms using Smart Materials
Abstract
Optimized Design for Active Noise and Vibration Control in Marine Platforms using Smart Materials:Noise emanating from machinery is not only poses tremendous health hazards to personal operating marine vessels, but also provides as a trigger to enemy attack. The noise can be airborne or structure borne. Structure borne noise presents a greater risk as far as the operation of the marine vessel is considered. It is always a designer~s dream to have a marine vessel that emits zero noise levels, although it is practically impossible to do so. There are two different approaches to alleviating the effects of noise, namely the passive and the active methodologies. In this project, we will address only some of the active methodologies using smart materials that can be developed for noise level reductions for marine structures applications. In this project the outstanding property of smart materials, that is conversion of one form of energy into another, will be utilized to perform active noise control in ship structures. Typically the proposed methodologies based on path treatment of the vibration conduits to reduce the structure borne noise. The methodologies will identify the placement of smart sensors/actuators through a robust physics based mechanics model and will adopt a suitable control strategy to alleviate the noise levels in and enclosed ship chamber(s). 2.Structure borne noise and sonar noise signal generation, identification, classification and modification is important of naval ships and submarines and has great potential for our fleet.3. Code 33, 34 and 32 are interested as are NSWC-Carderock and NUWC-Newport.4. Innovative algorithms and methodology, peer reviewed publications. NUWC and NSWC can test the methodology after development.
