| 摘要: |
| 针对一体化弹丸弹托易分离性和轻质化的设计要求，构建弹托迎风窝参数化外形模型，基于激波和膨胀波理论建立弹托气动力计算模型；以弹托分离加速度和弹托质量综合最优为目标函数，采用遗传算法对弹托迎风窝的外形参数进行优化设计，从而得到弹托迎风窝的优化外形。以中口径尾翼稳定脱壳穿甲弹的弹托设计为例，采用提出的优化设计模型对其迎风窝结构进行优化设计，并采用基于动网格技术的弹托分离仿真模型验证其最优性。仿真结果表明：所提优化模型能够得到最优的弹托迎风窝结构；针对现有的中口径尾翼稳定脱壳穿甲弹，可进一步对其弹托结构进行优化，以提高其分离快速性。 |

| Abstract: |
| Aiming at the design requirements of easy separation and light mass for the sabot of integrated launch projectile, an optimization design model was obtained by combining the aerodynamic calculation model by the genetic algorithm, in which the aerodynamic calculation model was established on the basis of the theory of shock and expansion wave through building the parameterized structure model for windward nest. And the discard acceleration and sabot′s mass were used as the indicators to build performance function. Taking the sabot design of armor piercing fin stabilized discarding sabot of medium caliber as an example, the proposed optimization model was used for the optimum structural design of the windward nest, and the simulation model of sabot discard based on dynamic grid technique was adopted to verify the optimality. Simulation results show that the proposed optimization design model can obtain the optimal wind′s eye of the sabot; in view of the existing armor piercing fin stabilized discarding sabot of medium caliber, the sabot structure can be further optimized to improve its rapidity. |
