舰艇摇摆作用下火炮射击诸元求解模型分析

摘要

通过研究摇摆运动作用下目标相对运动规律的变化,分析了摇摆运动对射击诸元精度产生影响的机理,指出了主要原因在于目标运动模型误差增加、提前点偏差增加.在研究弹丸膛外运动模型的基础上,分析并建立了基于迭代方法的射击诸元求解模型,并在此基础上建立了摇摆运动补偿模型,实现了对舰艇和甲板摇摆运动的有效补偿;建立了仿真模型,并设计了仿真实例对模型的有效性进行了验证,同时也通过实例验证了摇摆运动对于射击精度的影响原理分析的合理性.研究的结论和设计的模型对于进一步改进射击理论、研究射击技术提供了理论参考.%Through researching the change of the target's motion law under the influence of swaying,the mechanism of the effect of swaying on firing accuracy has been analyzed,and the increase of the target's motion model error and deviation of advance point have been figured out to be the principal cause.The model for solving firing data based on iteration has been analyzed and built based on the research on model of projectile's movement out of barrel.What's more,the model for compensating swaying has been built,and the swaying motion of the ship and board has been effectively compensated.The simulation model and example have been designed to verify the effectiveness of the whole model,and the rationality of the analysis on the mechanism of influence on firing accuracy caused by swaying has been proved.The model and the conclusion can be used for improving the firing theory and firing technology.
