摘要
分析了船体变形的原因、种类,以及船体变形对航姿信息的影响;介绍了监测船体变形的四种结构力学方法和包括惯性测量匹配法在内的三种船舶航行实时监测法,以及GPS姿态测量在船体变形监测中的应用。着重讨论了惯性测量匹配法测定船体变形技术在火控系统、舰载飞机和舰载导弹惯导系统传递对准、磁测量船、其它物理测量船等方面的应用。最后针对位于舰船的中心航姿系统和局部基准部位的陀螺和加速度计等测量部件的不同配置,详细给出了用惯性测量匹配法测定并消除船体变形影响的三种实施方案,比较了各方案的特点、计算过程和系统输出数据。这些方案对于在役舰船和现代舰船的船体变形监测和航向姿态修正具有借鉴作用。
Ship hull deformation and its influence on attitude/heading information were analyzed. Four structural mechanics methods of monitoring deformation, three real-time monitoring methods for ship＇s navigation including the inertial measurement matching method, and the application of GPS attitude measurement in monitoring deformation were introduced. As a result, the application of inertial measurement matching method in fire control system, shipborne plane and shipborne missile inertial system transfer alignment, magnetic field measuring ship, and other kinds of measuring ship was discussed. In the end, based on various configurations of measurement unit in the central attitude/heading system and the local reference place and using inertial measurement matching method, three schemes for ship hull deformation monitoring and attitude/heading information correction were described in detail.
