摘要: |
舰炮的炮口扰动是影响舰炮射击精度的重要因素。为了减少舰炮的炮口扰动,优化身管结构,建立了柔性身管的ABAQUS有限元模型,将有限元模型的模态计算值与模态试验值进行比较,发现建立的柔性身管有限元模型是合理可行的。提出了混沌量子粒子群算法与动力学联合优化的方法,进行身管和炮口的多目标优化。优化结果表明,优化后炮口中心的线速度、角速度和角位移与优化前相比显著减小,身管质量有所降低,结构更加合理,该优化方法有效可行,为下一步全炮总体优化设计提供了一定的借鉴。 |

Abstract: |
The muzzle disturbance is an important factor of affecting the naval gun firing′s accuracy. In order to reduce the muzzle disturbance and optimize the barrel structure, the ABAQUS finite element model of flexible barrel was established, and the modal calculation results of the model were compared with the modal test values, which proves that the established flexible finite element model is effective. A method of new quantum chaos particle swarm optimization algorithm and dynamic joint optimization was proposed to carry out multi-objective optimization of the artillery recoil mechanism. Optimization results indicate that the line speed, angular velocity and angular displacement of optimized muzzle center are significantly reduced when compared with that before optimization, the barrel mass is reduced, and the structure is more reasonable. This indicates that the optimization method is effective and feasible, and can provide reference for the overall design of the whole naval gun. |
