摘　　要：舰船在海浪中发生的弹性变形会对安装在其上的惯导系统对准精度产生影响,因此需要计算舰船的弹性变形,以补偿局部姿态误差。本方法基于梁理论,采用三维水弹性方法计算舰船在随机海浪中任意战位点处的相对三维角变形,并对船体的变形规律进行分析,供设计者参考使用。The warship hull＇s elasticity deformation in wave influences the alignment precision of inertial navigation. It is necessary to calculate the deformation to compensate the local attitude error. Based the beam theory,three-dimensional hydroelasticity method is used to calculate the three-dimensional angular deformation between arbitrary points of warships in random wave. The law of angular deformation is analyzed. The result can be used by designers.
