某型舰炮弹炮耦合对炮口振动影响的研究

摘要

According to the gun muzzle vibration influence on launch state of naval gun systems, a kinetic model of recoiling parts and the coupling of gun and bomb to a certain naval gun was built by using the software of ANSYS. Based on these models, use the finite element analysis method for analysis, draw a conclusion of that the amplitude of the gun muzzle place from begin to increase gradually, bore the projectile instantaneous maximum, and then decrease gradually until reduced to the minimum. The analysis results show that this method can simulate the real coupling process of gun and bomb of naval gun, acquire the influence of the coupling of gun and bomb on gun muzzle vibration.%　　针对炮口振动会影响舰炮系统发射状态的问题，运用 ANSYS 软件建立了某型舰炮的后坐部分动力学模型和弹炮耦合动力学模型。基于此模型，采用有限元分析法进行分析，得出：炮口处的振幅从开始逐渐增大，在弹丸出膛瞬间到达最大值，然后逐渐减小，直至减到最小值。分析结果表明：该方法能够较真实得模拟舰炮弹炮耦合过程，得到弹炮耦合对炮口振动的影响结果。
