水面提拉式发射动力装置的发射动力组件结构参数优化

摘要

Mathematical mode of the surface push-pull cyclinder torpedo launcher is built.Configuration and interior ballistic parameter is optimized with particle swarm algorithm.As refereed to several parameters and they are different in degree and range,normalization is applied to translate multi-objective optimization to single-object optimization,and penalty function method is used to deal with restriction condition.The result of optimization shows that the optimized configuration parameter meet the requirements of launching well and small volume,light weight and better interior ballistic performance.%建立了水面提拉式发射装置发射过程数学模型,运用粒子群优化算法对水面提拉式发射装置的发射动力组件结构参数和内弹道参数进行了优化计算.在优化过程中,运用参数归一化方法对单位及数值数量级不同的多参数进行了无量纲值处理后,把多目标优化问题转化为单目标优化问题,并采用罚函数法处理约束条件.优化结果表明,优化后的发射动力组件的结构参数不但满足发射要求,而且组件的体积小、质量轻,可实现的发射内弹道性能更好.
