海浪作用下舰载武器IMU输出建模与仿真实现

Modeling and Simulation for IMU of Shipboard Weapons in the Condition of Waves

摘要:

在海浪作用下舰船载体运动方程极为复杂,文章在对运动方程不作任何简化的情况下,给出了方程的数值解,并在此基础上,考虑杆臂效应的存在,给出了舰载武器的IMU输出模型的仿真实现。研究表明,利用此精确模型能够直接对舰载武器IMU的性能作出有效评估,从而大大减少测评周期和成本。

Abstract:

The equation that indicates the movement of body reference frame under inertial reference frame is very complex, this paper has given the numerical solution to the equation without simplifying the equation. Having taken lever-arm effect into consideration. The method is useful in evaluating the characteristic of the ship-fixed IMU in the condition of without actual data.
