摘要
为实现迫弹质量的仿真检测,根据迫弹生产和质量检测特点,本文提出一种用于迫弹散布密集度仿真评估的经典内弹道模型,引入弹丸结构修正公式和射角修正公式,并给出了分步计算方法。以某型迫弹为对象的仿真实例表明,仿真结果与靶场试验结果相一致,模型可信度高。
In accordmace with the characteristic of the mortar cartridge manufacture and quality test, an improved simulation model for mortar interior ballistics was proposed, which can be used to evaluate virtually the range and ground dispersion of motor cartridge, to achieve the virtual test of mortar cartridge quality, The effects of the angle of departure and the error of motor cartridge shape were modified in this model. The step by step computation method was used, in which the course of interior ballistics was divided four interconnected stages, Finally, this model was applied to simulate the initial velocity of a certain motor cartridge. The simulation results show this improved simulation model is credible, which agree well with the range test results.
