摘要:
针对某电磁弹射式火箭炮后坐力巨大造成的发射系统结构变形和强度破坏问题,该文应用粘滞流体流经小孔产生阻尼力原理,设计了一种小行程液压缓冲装置。该装置能够在火箭炮允许的弹性变形范围内,以较小的行程实现火箭炮后坐力缓冲。根据有限元方法得到的缓冲行程,设计了缓冲装置的后坐运动轨迹,并推导求解了该运动轨迹下节流孔开口面积的变化规律。通过控制节流孔的开口面积来控制系统流量,以使后坐按照设计的轨迹运动。针对不同的缓冲行程,利用AMEsim和Adams进行了液固联合仿真。结果表明,该文设计的缓冲装置能够实现小行程时某电磁弹射式火箭炮的后坐力缓冲。
Abstract:
Aiming at the problem of structural deformation and strength damage of launch system caused by large recoil force of the electromagnetic ejection rocket launcher,a small stroke hydraulic buffer device is designed based on the principle of viscous fluid flowing through small holes to produce damping force. The device can realize recoil force buffering with small stroke within the allowable elastic deformation range of the rocket launcher. According to the buffer stroke obtained by the finite element method,the recoil motion track of the buffer device is designed,and the variation law of the throttle valve opening area under the motion track is deduced and solved. By controlling opening area of the throttle valve,the system flow is controlled to make the recoil move according to the designed trajectory. The AMESim and the Adams are used to simulate the liquid-solid joint under different buffer strokes. The results show that the buffer device in this paper can realize recoil force buffering in small stroke.
