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几种实施方案。分别讨论了在中心航姿系统部位和局部基准部位是否安装加速度计和速率陀螺时的不同情况,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。对各种方案进行了分析比较,指出了各自的优缺点,为惯性测量匹配法在实船上的应用打下了基础。The reasons of ship deformation are introduced.The influence on attitude parameters of ship deformation is analyzed in detail.Several schemes of measuring ship deformation using inertial measurement matching on real ships are also analyzed in detail.The different situation is discussed that whether installing accelerometers and speed gyros at central navigation attitude system position and local benchmark position or not.The formulations of the deformation angle,navigation attitude angle and swing velocity at local benchmark position are given.The different schemes are analyzed and compared respectively. Their advantages and disadvantages are shown.This creates the foundation for the application of inertial measurement matching on real ships.
