舰船柴油机组状态监测及减振效能在线评估系统

摘要

Active vibration isolation is a potential technology to solve the low-frequency noise problem of vessels. However, the active isolation experimental system (AIES) of diesel units of vessels has some shortcomings such as long experimental duration, messy test fields and huge in-situ noise. Besides, it is unlikely to make a global evaluation of noise reduction effect for the diesel units according to the information at the limited controlling points only. In this paper, a system with on-line monitoring, on-line assessment, data acquisition and recording and video surveillance is developed for the AIES. The function of on-line monitoring and assessment is emphasized. The experiment showed that the system can save time, improve work efficiency and comfort, which met the expected requirements.%主动隔振技术是一种具有治理舰船低频噪声潜力的新技术。针对舰船柴油机组主动隔振试验系统试验时间长、现场混乱、噪声大以及局部有限控制点信息无法进行全局减振效能评估的缺点，特研发一套柴油机组状态监测及减振效能在线评估系统。该系统具有状态在线监测、减振效能在线评估、数据采集和记录以及试验现场视频监控等功能，现场试验显示该系统可以节省时间，提高试验工作效率和工作舒适度，达到预期设计的目的和效果。
