| 摘 要： | 安装于鱼雷捷联惯性系统中的惯性测量装置不可避免地存在安装位置误差，从而引起了尺寸效应。文章对尺寸效应引起的系统误差进行了分析，仿真结果表明，只要惯性测量装置偏离雷体摇摆中心距离较小，且鱼雷作旋回运动的速度较低、时间较短，则可以忽略尺寸效应对系统导航性能的影响。

| Abstract: | Installation position error of the inertial measurement unit in the torpedo strap-down inertial system is existent inevitably, which arouse size effect. In this paper, the system error caused by size effect is analyzed. The size effect impact on navigation performance is proved to be negligible, as long as the inertial unit position deviation from rocking center of the torpedo body is slight and the torpedo turning movement duration is short in low velocity. |
