均匀试验设计法在导弹射击精度计算中的应用

The Application of Uniform Experimental Design to Missile Firing Accuracy Calculation

应用均匀试验设计方法 ,根据“均匀分散”的思想 ,把影响导弹发射的 11个主要参数按照 31个水平进行试验设计 .采用U31( 3111)均匀设计表及试验方案 ,对某飞航导弹进行了 31次导弹武器系统射击精度六自由度模拟仿真试验 .计算结果表明 ,计算次数大幅度减少 ,计算结果准确可信 ,11个因素对射击精度的影响大小和变化规律与导弹实际精度试验数据相吻合 .通过对仿真结果处理 ,给出了导弹脱靶量随发射条件变化的预报公式 .与常规试验方法相比 ,充分体现了均匀试验设计法的科学性和先进性 .

Uniform experimental design is applied by the idea of uniform disperion,using U 31 (31 11 )uniform desigh table and test scheme,dividing eleven main factors which affectted missile firing accuracy into thirty one levels,six freedom simulation about some cruise missile has been done.Results show that calculation times reduces rapidly,the results are reasonable,eleven factors effect on firing accuracy is agree with real parameters,missile missdistance prognostic equation about firing conditions is given by treating simulation results.Comparing with conventional test method,the uniform experimental design has scientific and advanced performance.
