| 摘 要： | 运用有限元方法计算出身管在自重作用下不同射角时炮口端的弯曲度，得出炮口角随射角的变化关系，分析身管自重弯曲对火炮射击精度的影响，并建立身管弯曲的修正模型。证明身管的自重弯曲是影响射击精度的不可忽略的因素，提出了一种计算弯曲度和修正射击的方法。

| Abstract: | The gun barrel＇ s curve deflection under the gravity in different elevations is solved with finite element method, the relations between angle of gun and fire is obtained, the influence of gun barrel＇ s weight on target accuracy is analysed and the correction model built. Gun barrel＇ s weight curve is a factor that can＇ t be ignored, and a method of calculation of deflection and correction is put forward. |
