Analysis of naval gun vibration based on Gauss minimum constraint theory

The dynamic model of complicated naval gun system was established with Gauss minimum constraint method based on rigid multi-body dynamics theory. Combined with correlative experiment parameters, the fire process of the whole gun system was numerically calculated. The result indicates that the deck stiffness is a main factor affecting the gun vibration. Therefore, designing a suitable elevating mechanism can effectively improve the vibration performance of the tube. The method and the result are of certain reference value to correlative engineering research and calculation, and can also provide a theoretical basis for the design of naval guns.
