Abstract

The optimization of anti-vibration performance of barrel of naval gun is studied based on the firing accuracy of naval gun during continuous firing. According to the actual model of barrel, a simplified model of the three-section beam structure of barrel is put forward. And then a mathematical model of the barrel stiffness optimization is established, and the stiffness model of barrel is deduced. The sensitivity analysis method is used to obtain the sensitivity analysis map of barrel stiffness and mass, thus determining the optimized parameters. The ANSYS software is used for the multi-objective optimization of the anti-vibration performance of barrel. The optimal solution of barrel optimization was obtained and compared with the actual barrel model. The results show that the effective design variables of barrel could be changed to improve the dynamic performance of barrel. After the anti-vibration performance is optimized，the first order natural frequency is increased by 17.99%, and the mass of barrel is reduced by 6.12%. Key
