| 摘 要： | 该文应用内弹道、气体动力学和优化设计理论建立了抛放弹弹射机构的优化设计模型。针对某一类型的弹射装置，应用复合形优化方法对影响悬挂物(导弹或炸弹)的弹射性能的若干参数进行了优化设计。计算实例表明，通过优化设计得出的设计变量参数，可以使悬挂物的最大弹射加速度明显减少。该优化设计模型为改进现有型号的气动力工作性能提供了有力工具。

| Abstract: | An optimum design model of ejection device with blank cartridge is established based on the theories of interior ballistics, gas dynamics and optimization. Aiming at a certain kind of ejection device, a compound simplex method is used to optimize several parameters influencing ejection process of the suspender (e.g. missile or bomb). It is shown by calculation that the maximum acceleration of the suspender can be obviously decreased by the parameters gotten by optimization. Therefore, the optimization model provides a helpful tool to improve the gas dynamics characteristics of ejection devices used in practice now. |
