| 摘 要： | 利用坐标变换得到射击诸元解算模型,根据得到的射击诸元解算模型的教学表达式,用隐函数微分法得到每个射击诸元影响因素的误差传递系数,利用精度分析模型建立射击诸元精度表达式.然后用均匀试验设计法确定典型射击条件,在这些典型射击条件下,计算各误差传递系数,根据给定的某组火控系统各设备的精度指标,进而计算火控系统各典型射击条件下的火控系统精度值,并确定合理的精度指标期望值.要获得这组火控系统各设备的精度指标下,任意指定射击条件下的系统精度值,利用已算出的各典型射击条件下的系统精度值,采用逐步回归分析方法,可获得火控系统各射击诸元参数的精度与各射击条件的函数关系近似表达式.

| Abstract: | Through the coordinate transform to get the calculating model of shoot elements, and based on the mathematics calculating model to get every error transmission coefficient of the shoot elements influence factor, utilization accuracy analysis model is implemented to build shoot elements accuracy expression. Then it uses the equality examination design to define the typical shooting condition, and under this shooting condition referred above, counts each error transmission coefficient, that according to the e... |
