摘　　要：提出一种基于代理模型的固体火箭发动机装药优化设计方法。将代理模型技术用于基于Level Set的固体火箭发动机装药设计,并提出了基于Pareto前沿采样的并行加点准则,进一步提升算法性能。以后翼柱型装药为例,以推力平稳为设计目标,得到了优良的推力性能,验证了方法的有效性。An optimization design method for solid rockot motor grain based on surrogate model was proposed. To enhance the efficiency of surrogate based SRM grain design, a Pareto front based parallel infill criteria was proposed. Taking a finocyl grain de- sign as an example, the variance of the thrust was minimized and a smooth thrust-time curve was obtained, which proves the effec- tiveness of the method.
