改进型实数编码遗传算法在内弹道优化中的应用

为实现内弹道装药结构的优化设计方案,提出将改进型遗传算法应用于内弹道优化数学模型.在基本遗传算法的基础上采用实数编码方式并对遗传操作进行改进,引入最优保留策略,使其更适合内弹道优化模型的复杂非线性.建立了具有代表性的某高炮内弹道装药优化设计模型,通过计算机仿真得到优化方案,并与采用模式搜索法和基本遗传算法得到的优化方案进行对比,结果表明,采用改进遗传算法进行内弹道优化是有效可行的.

Application of Improved Real-coded Genetic Algorithm in Interior Ballistic Optimization

To realize optimization design of charge structure of interior ballistics,the improved genetic algorithm(IGA) was applied to the calculation model.The simple GA(SGA) which was much more suitable for the non-linear mathematic model was improved by using real-code,ameliorating genetic operations and the best-keeping strategy was introduced at the same time.The optimization design model of charge structure of representative antiaircraft gun was built.The optimization scheme was obtained through simulation,whic...
