摘要

为研究齿侧间隙作用下小口径车载机关炮身管的振动响应情况,建立了含齿侧间隙的高低机简化模型,给出了接触碰撞力学模型的参数辨识方法。在ADAMS软件中将路面激励简化为作用在齿轮上的正弦位移信号对模型进行动力学仿真,对比分析了有无齿侧间隙作用下身管的振动响应频率、炮口的振动位移和速度变化情况。结果表明齿侧间隙作用下火炮发生多频变幅连续振荡,破坏了火炮的射弹初始条件,降低了火炮射击精度。

Abstract

Aiming at the study the vibration response frequency and its displacement of small-caliber vehicular gun tube,the simplified model of elevating mechanism including gear backlash is established and the method of parameter identification of contact-impact mechanical model is given.Through the dynamics simulation by applying sinusoidal signal in ADAMS,the vibration response frequency of tube with backlash are compared with no backlash,and its displacement and velocity are obtained.The results show that the continuous multi-frequency phenomenon occurred with large range,which has a bad effect on projectile initial conditions and reduces firing accuracy.Based on this,the theoretical guidance in structure optimization of gun control and firing accuracy improvement is provided.
