| 中文摘要 | 为提升超短基线水声定位系统的定位精度,设计了一种新型超短基线换能器的定位装置。该装置采用双出轴多排链结构进行动力传递,用直线导轨进行主轴导向和定位,并用大型自密封滑动轴承进行定向。采用ANSYS进行有限元分析,确定定位主轴在伸出船体3 m并且船体运动不大于6节航速时,其偏摆角在0.1°以内,远小于当前超短基线定位系统1°偏摆角的要求,并且垂直定位精度在0.2 mm以内。陆上模拟试验,也证实了设备的性能可靠,维修保养方便。实践证明:该设计方案定位精度的提升有利于提升超短基线整体系统定位精度。; A new typed positioning mechanism was described,which can promote the accuracy of ultra short base line(USBL) acoustic positioning system.The mechanism adopts dual-shaft multi-row chain structure for power transmission,using linear guideway for guidance and positioning of the spindle and employ large self-sealing plain bearings for directional.The finite element method is used to make sure that the deflection angle is less than 0.1皏ia ANSYS,which is far less than 1皌hat is the current deflection angle,while the positioning spindle out of the hull 3 meters and the hull's speed not more than 6 knots.And also the positioning accuracy is less than 0.2 mm.The onshore test confirms the reliability and maintenance of the mechanism.It is provided that the accuracy of the mechanism improves the overall positioning accuracy of the USBL. |
