摘要
用逐步回归分析法研究弹丸初速、弹质量和弹丸偏心距等因素对车载炮射击密集度的影响,建立了影响程度逐步回归分析算法,并以某车载炮的密集度性能实弹射击试验数据为基础,对试验数据中的落点坐标进行了相关性分析,研究了各因素对该车载炮射击密集度的影响.回归分析结果表明,影响弹丸纵向射程的主要因素是初速,影响横向侧偏的主要因素是弹质量.回归分析结果与实弹射击结果相吻合,逐步回归分析法用于分析车载炮射击密集度的影响因素是可行性的、有效的.
The firingdispersion of wheeled-artillery affected by the offsetting of projectile was studied by stepwise regression of the method was established. The relativity analysis for i based on the live firing-test data for the firing dispersion of a c the initial velocity, the weight and analysis method,and the algorithm coordi wheele nates was carried out d-artillery. The effectsof the effect factors on factor affecting late affecting ral displa firing dispersion w longitudinal range ere discussed projectile cement is the mass of projectile accords well with the live firing phenomena. feasi 1S T ble regression analysis shows that the tial velocity, and the major factor results of the regression analysis and effective to stepwise regression analysis method to analyzing effect factors affecting wheeled artillery. apply the proposed firing dispersion of
