某火箭弹制造缺陷对起始扰动影响的仿真研究

A Simulative Study on the Influence of Manufacturing Imperfection of a Rocket upon the Initial Disturbance

目的 研究火箭弹制造缺陷对起始扰动的影响． 方法 根据火箭武器系统结构特点， 建立火箭起始扰动发射动力学模型， 应用蒙特卡洛方法对火箭发射过程进行数值仿真． 结果 得出了火箭弹质量偏心、动不平衡、推力偏心等对火箭弹起始扰动的影响规律． 结论 火箭弹缺陷对起始扰动的影响不容忽视，

Aim To study the influences of various types of manufacturing imperfections of a rocket upon the initial disturbance. Methods According to the construction of the weapon system, a model for launching dynamics is established. Monte Carlo method is applied to numerical simulation of rocket launching. Results The influences of rocket static unbalance, dynamic unequilibrium, and propulsion eccentricity was obtained. Conclusion The effects of rocket manufacturing imperfection to the initial disturbance can not be ignored, which must be considered in rocket weapon development.
