某炮弹立靶密度集度的影响因素分析

从发射动力学的角度,分析了影响某炮弹立靶密集度的因素.火炮种类、火炮状态、身管温度、地面种类、轮胎气压等试验条件变化会改变发射系统振动特性,射击过程中身管温度升高会导致身管指向变化,拔弹力和弹药保温、搬运、装填等试验操作会影响到弹丸在膛内的运动.这些都是影响弹丸起始扰动的因素.试验结果表明,试验条件、弹药准备以及人员操作等规范后,该炮弹立靶密集度得到了大幅提高.

Analysis on Factors Influencing Vertical Target Dispersion of Projectile

From the point of launch dynamics, the factors influencing the vertical target dispersion of projectile were analyzed. The change of vibration characteristics of launch system can be caused by the difference of test conditions, such as the style of gun, the status of gun, the temperature of barrel, the style of ground and the pressure of tire. The change of barrel orientation can be caused by the temperature rising of barrel during firing process. The movement of projectile in gun tube can be influenced by bullet pull and the test operation, such as the temperature of ammunition, conveying and loading cartridge. All these are the factors that influence the initial disturbance of projectile. After the test conditions, ammunition preparing and personnel operation are regulated, the vertical target dispersion of projectile is improved greatly.
