水平弹射装置是空基发射平台中用以提升自身的弹射性能和降低对发射平台影响的核心部件。文中针对某活塞式水平弹射装置,以短时间、低过载、高平稳为目标,将非支配排序遗传算法应用于弹射内弹道的优化设计中,对装药量、初始容积、喷管喉径进行了系统优化。为了验证优化结果,采用优化后的参数开展了水平弹射试验,结果表明弹射过程时间减少了1.6%,出筒速度增加了14.5%,过载降低了6.1%,加速度标准差减小了48.4%,有效改善了弹射整体性能。编写的优化程序对多目标优化问题有较好的普适性,可根据设计需求提供多种优化方案,为弹射装置的改进设计研究提供了借鉴。

Horizontal ejection devices are mostly used in space-based launching platforms, so it is of great significance to improve their ejection performance and reduce the impact on launching platforms for the overall performance of weapon systems. In this paper, aiming at a piston-type horizontal ejection device, aiming at short time, low overload and high stability, the non-dominated sorting genetic algorithm was applied to the optimization design of ejection interior ballistics, and the charge quantity, initial volume and nozzle throat diameter were systematically optimized. In order to verify the optimization results, the horizontal ejection test was carried out with the optimized parameters. The results show that the ejection process time was reduced by 1.6%, the ejection speed was increased by 14.5%, the overload was reduced by 6.1%, and the standard deviation of acceleration was reduced by 48.4%, which effectively improved the overall ejection performance. The optimization program has good universality for multi-objective optimization problems, and can provide a variety of optimization schemes according to design requirements, which provides a reference for improving the design of ejection devices.
