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.
