Abstract:
In view of that the muzzle vibration caused by the rapid servo affects the firing accuracy of the rocket weapon launch system,the muzzle vibration of the ultra-short-range defensive weapon system is analyzed by the multi-body dynamics method.Taking minimuming the muzzle vibration linear velocity as the optimum object,the rotating body torsional stiffness,the pitching body torsional stiffness and three submarine base stiffnesses are optimized,and the five optimal equivalent stiffnesses are obtained.The dynamics properties of the system before and after optimization are compared.The results show that the residual system vibration is greatly reduced and decays soon after optimization,and the rational match of different structure stiffnesses obviously decreases the oscillation amplitude of the muzzle vibration linear velocity during the braking phase.
