为了得到无喷管助推器药柱设计的最优解,采用无喷管助推器一维非定常内弹道计算方法和粒子群模式搜索混合优化算法,构建了无喷管助推器药柱优化设计框架,优化框架中粒子群算法用于全局搜索,模式搜索算法用于局部搜索。对圆柱内孔装药无喷管助推器的药柱结构进行了优化设计,最大化总冲设计在不增大峰值压强的条件下总冲提升了5.4%,最小化峰值压强设计在总冲不降低的条件下峰值压强降低了33.8%,表明设计框架适用于无喷管助推器药柱优化设计过程,能够满足不同药柱设计的需求,混合优化算法的采用大大降低了优化设计代价。
In order to get the optimal solution of nozzleless booster design, a one-dimensional unsteady interior ballistic calculation method without particle thruster and a particle swarm optimization (PSO) search hybrid optimization algorithm are used to build a nozzleless booster cartridge Optimize the design framework, Particle Swarm Optimization in the framework of optimization for global search, pattern search algorithm for local search. Optimized design of the column structure of the nozzle without inner tube charge was designed to maximize the overall red design without increasing the peak pressure of the total red rise 5.4%, the minimum peak pressure design in the total red The peak pressure is reduced by 33.8% under the condition of no decrease, which indicates that the design framework is suitable for the optimization design process of the nozzleless booster and can meet the design requirements of different columns. The adoption of hybrid optimization algorithm greatly reduces the cost of optimization design.
