摘 要:为研究反后坐装置布置结构对射击精度的影响,针对某轮式大口径火炮的结构特点和发射原理进行受力分析与炮口振动影响因素分析,建立了轮式大口径火炮整车发射刚柔耦合多体系统动力学模型,通过数值计算获得了反后坐装置不同布置的后坐运动规律,在此基础上采用烟花算法分别对3种反后坐装置布置结构进行优化分析,确定了3种结构下对射击精度的影响最小的布置方案,优化后比优化前的炮口扰动分别减小了39.6%、42.4%、28.2%。研究结果表明所提出的数值仿真与烟花算法相结合的优化方法具有可行性,且双制退机双复进机斜向中心对称布置的射击精度要优于其他结构。In order to study the impact of the arrangement of recoil mechanisms on firing accuracy,force analysis and muzzle vibration influencing factors were conducted according to the structural features and launching principles of a large-caliber wheeled gun.A dynamic model of the rigid-flexible coupling multi-body system of the entire large-caliber wheeled gun was successfully established.The recoil movement law of different arrangements of the recoil mechanism was obtained by numerical calculation.Three arrangements of the recoil mechanisms were improved and subjected to fireworks algorithm analysis,and the layout scheme with the least impact on shooting accuracy was finally determined.The muzzle disturbance after optimization was reduced by 39.6%,42.4%and 28.2%respectively compared with that before optimization.The research results show that the proposed optimization method combining numerical simulation with the fireworks algorithm is feasible.They also show that the arrangement with two symmetrically-arranged recoil brakes and counter-recoil mechanisms offset from the center has better firing accuracy than other arrangements.
