摘要:
为改变传统大口径舰炮旁侧路的复杂供弹模式,提出了一种应用中心单线摆弹机理的中腹供弹方式。应用惯量等效法,对假设为刚体的中腹摆弹机构进行分析,获得了摆弹的初始动力学参量。基于一次近似理论,应用一致质量有限元离散化方法,将中腹摆弹臂划分为若干单元。采用弧坐标分量和笛卡尔坐标分量共同描述柔性摆弹臂的变形场及运动关系。应用Hamilton原理建立中腹摆弹机构的刚-柔耦合动力学方程。仿真结果显示:在高射速、大摆角的情况下,中腹摆弹机构存在较大的摆弹误差; 在中腹供弹系统的研究中,应考虑摆弹臂的柔性变形对摆弹精度的影响。
Abstract:
To change the complex shell-feeding mode of traditional large caliber naval gun flanking paths,an abdominal shell-feeding method using the center single line shell-swinging mechanism is proposed.The abdominal shell-swinging mechanism under the rigid assumption conditions is analyzed with the inertia equivalence method,and the initial dynamic parameters of the shell-swinging are obtained.Based on the first-order approximation theory,the abdominal shell-swinging arm is divided into several elements using the consistent quality finite element discrete method.The deformation filed and motion relations of the flexible shell-swinging arm are described jointly using the arc and Cartesian coordinate components.The rigid-flexible coupling dynamics equation of the abdominal shell-swinging mechanism is established utilizing the Hamilton principle.The numerical simulations show that the abdominal shell-swinging mechanism with high firing rate and big swing angle has larger shell-swinging error.The affection of the flexibility deformation of shell-swinging arm on the shell-swinging accuracy should be considered in the research of abdominal shell-feeding system.
