为实时解算某型火箭发射装置俯仰系统重力矩,基于质点系等效质心原理推导出任意载弹模式下重力矩算法模型,采用Matlab编程实现算法并同Pro/E测量计算实际值对比分析。仿真结果表明,该算法满足任意载弹模式下重力矩实时解算要求并达到较高精度,有效解决当前采用Pro/E软件测量并计算重力矩方法工作量大且通用性差等缺点,极大的提高研究效率。

In order to calculate load of gravity moment of a certain type of rocket launcher in real time, based on the principle of equivalent mass center of mass of a particle system, the model function of gravity moment in any load mode was deduced and programmed with Matlab, and compared with actual results measured and calculated by Pro/E software. Simulation results show that this kind of algorithm can satisfy real-time solution of gravity moment in any load mode, settles effectively current use of Pro/E software to measure and calculate gravity moment method which has series of shortcomings like a large amount of work and poor generality, which can greatly improve research efficiency.
