摘　　要：为提高小口径榴弹设计性能,缩短设计周期,建立了包括结构、内弹道、外弹道、杀伤威力以及武器后坐力5个分析计算模型的集成优化设计模型.应用模拟退火算法,分别以最大杀伤面积、最短弹丸飞行时间以及杀伤威力与武器后坐力综合性能为目标对榴弹进行了集成优化设计.与原设计相比,杀伤威力提高39%,弹丸飞行时间缩短5%,杀伤威力提高38%,后坐力降低44%.得到了榴弹各目标性能最优时的结构参数、装药参数、射击条件及单兵武器缓冲器参数.该研究为小口径榴弹的设计提供了一种新方法.To improve the design performances of small caliber grenade and shorten the design cycle, an integrated optimization design model involved structure, interior ballistics, exterior ballistics, lethal power and weapon recoil force, was set up. Separately aiming at the maximum lethal power, the minimum flying time of grenade, the optimal combination properties of lethal power and recoil force, the model was optimized by using the simulated annealing algorithm. Compared with the original design, the lethal power improves 39%; the time decreases 5%; the lethal power improves 38%, and the recoil force decreases 44%. The parameters of structure, projectile filling, firing condition and bumper of the individual soldier automatic weapon were also obtained. The study offers a new research technique for the optimization design of small caliber grenade.
