摘要:
为了对多管火箭射击密集度进行评价、设计、控制,定量分析了随机因素对射击密集度的影响。基于火箭弹飞行动力学方程,综合考虑火箭弹加工及装配误差、起始扰动、风等随机因素对火箭弹飞行过程的影响。应用Sobol'全局灵敏度分析方法,得到了随机因素及其交互作用对落点的灵敏度值。通过与传统密集度误差分析方法对比,将其引申为对射击密集度的影响权重。分析结果表明:随着现代测试、加工技术的发展,特别在小射角下,起始扰动已成为影响射击密集度的最主要因素。
Abstract:
To evaluate,design and control the firing dispersion of multiple launch rockets system scientifically,the influences of random factors on firing dispersion are analyzed quantitatively.The influences of processing and assembly errors,initial disturbances and the wind on flight are considered based on the flight dynamics equations of rockets.The sensitivities of affecting factors and their coupling actions relative to impact points are abtained using the Sobol' global sensitivity analysis method.Compared with traditional error analysis methods,the sensitivities are extended to be the weights of affecting factors in meaning.The analysis results show that,along with the development of modern measurement and processing technique,initial disturbances are the major factors influencing the firing dispersion especially in small firing angles.
