摘　　要：介绍了船体变形的产生原因,详细分析了船体变形对航姿参数的影响和惯性测量匹配在实船上测量船体变形时的应用。讨论了在中心航姿系统部位安装速率陀螺,在局部基准部位安装速率陀螺和加速度计时船体变形的测量情况,具体推导了变形角、局部基准部位的航姿角和摇摆线速度的计算公式,为惯性测量匹配法在我国舰船上的实际应用打下了基础。The reasons of ship deformation are introduced. The influence on attitude parameters of ship deformation is analyzed in detail. Measuring ship deformation using inertial measurement matching on real ships are also analyzed in detail. The situation is discussed that installing speed gyros at central navigation attitude system position and installing aceelerometers and speed gyros at local benchmark position. The formulations of the deformation angle, navigation attitude angle and Swing velocity at local benchmark position are given. This creates the foundation for the application of inertial measurement matching on real ships in China.
