融合稳定性与炮口扰动的车载火炮参数优化

射击稳定性与射击密集度是体现车载火炮综合作战性能的关键指标,也是进行车炮匹配问题研究与优化的重要内容。针对稳定性参数与炮口扰动参数时空属性不同,在ADAMS中无法进行综合优化的难题,结合多体动力学仿真软件ADAMS、Box-Behnken试验设计方法及Matlab遗传算法工具箱等技术提出了融合射击稳定性与炮口扰动的组合优化方案,并基于某车载火炮虚拟样机对上述方法进行了验证。根据优化结果,某车载火炮车尾跳高、车尾侧移、炮口位移均获得较为明显的优化效果,为车载火炮车炮总体参数优化匹配研究奠定了基础。

Research on Matching Optimization of Vehicle Artillery with Firing Stability and Muzzle Vibration

The shooting stability and firing dispersion are the key indexes to reflect the combat capability of vehicle-mounted howitzer.In addition,they are very important to research and optimize the matching problem of vehicle and gun.Due to different temporal-spatial properties of stability parameters and muzzle disturbance parameters,it is difficult to comprehensively optimize parameters in ADAMS.Therefore,this article puts forward an optimization method combining shooting stability and muzzle disturbance based on the multi-body dynamic software ADAMS,Box-Behnken design method and Matlab genetic algorithm toolbox.Based on the virtual prototype of vehicle-mounted howitzer,the above methods were verified.Optimization results show that the optimization for indexes such as tail jump,lateral displacement of vehicle tail,and muzzle displacement are obvious,which lays the foundation for optimizing overall parameter matching of vehicle-mounted howitzer.
