Title The Design Optimization For An Artillery Recoil Mechanism
Abstract
In this thesis, the structural analysis of an artillery recoil mechanism was conducted, and the formulation rule of recoil resistance was studied. the force analysis of recoil mechanism was carried out according to the chamber pressure curve, and the dynamic analysis on recoil brake model during recoil stroke was studied using developed simulation program based on Matlab software. Usually，the change and optimization of recoil resistance can be succeeded by adjusting the structure size of the throttlling bar to change the area of liquid orifice associated the variation of recoil resistance. Therefor, the structural optimizatin for throttling bar of recoil mechanism was conducted in this thesis, using ISIGHT optimization software to obtain the optimal structure size of the throttling bar based on the dynamic model of recoil mechanism and various optimization algorithms. The maximal recoil resistance was reduced significantly by structure size optimiztion of the throttling bar, and the optimized recoil resistance curve was more smoothly compared to that without optimiztion process.

1.1 火炮及反后坐装置简介
火炮武器是各国军队陆海空装备数量最多，使用最频繁的武器种类，具有毁伤威力大，持续战斗力强，目标特征小，攻防性能兼备，反应速度快，操作文护简易，可靠性好，造价低廉，弹药种类丰富等特点，是其他任何武器不可替代的，在现代及未来战争中具有举足轻重的作用。随着高新技术在战场上的大量应用，战争形式在不断发生变化。未来战场对火炮的战术技术性能提出新的要求，促使火炮领域发生深刻的变化。各国在发展火炮自动武器的过程中，均以提高其射程，射速，威力，精度，快速反应能力和生存能力等综合作战性能为目标，将高新技术应用于常规武器，大幅提高其战术技术性能，使军队作战能力成倍增长[1]。
