Abstract :
The vibration of gun system affects its firing accuracy. Based on the Gauss minimum constraint principle the multi-body dynamic model of gun system was developed. The analytic expressions of the dynamic equations in closed form were deduced, and the means to simplify various external forces including the impact loading were provided. According to this dynamic equations and combining the correlative experimental parameters, the natural vibration frequencies of gun system were estimated, then the firing process was numerically simulated. Through the simulation analysis the relationships between structure parameters and muzzle vibration were presented. Further, the factors dominating the firing accuracy were determined. The results of simulation have instructional significance for improving the vibration performance, and increasing the firing accuracy. The multi-body modeling method adopted in this paper is also available for other weapon´s vibration analysis.
