舰船甲板挠曲变形动态检测技术研究

Research on Dynamic Detection Technology of Ship's Deck Deformation

基于卡尔曼滤波算法建立了舰船甲板变形动态检测系统的模型,其中舰船上的INS(主惯导系统)作为基准对舰船在海中航行的姿态进行实时动态检测,甲板上滑行的SINS(子惯导系统)检测甲板的实时形变量。利用微分几何得到真实的甲板挠曲变形量,并对模型进行仿真。结果表明,这种测量方法在实际应用中具有可行性。

The model of the ship’s deck deformation dynamic detection system was established based on the kalman filter algorithm. The INS( Main Inertial Navigation System) on the ship was used as a reference to perform real-time dynamic detection of the ship’s attitude in the sea,and the sliding SINS( Sub-Inertial Navigation System) on the deck was used to detect the real-time deformation of the deck. According to the differential geometry,the actual deflection of the deck was obtained,and the model was simulated. The results showthat this measurement method is feasible in practical engineering applications.
