舰船修理振动噪声测试与评估研究

Research on test and evaluation of vibration and noise during ship's repair

文章围绕舰船修理期间的振动噪声测试与评估开展了研究,阐述了修理振动噪声评估的原理和方法,分析了振动噪声测试的步骤及要求,在此基础上对某舰船修理前后设备振动状态进行了评估,对振动状态恶化的设备进行了深入研究,提出了声学质量控制措施与建议,为舰船振动噪声整改提供了依据和参考。

The thesis focused on the test and evaluation of vibration and noise during ship＇s repair. The principles and methods for evaluating vibration and noise were researched, the test procedures and requirements were carried out. On the basis, the vibration state of equipments was evaluated separately before and after the ship＇s repair while the further study was given to the equipments on which the vibration being worse. Both measures and suggestion for acoustic quality controlling were also provided, which were significant and important reference for ships＇mending.
