摘要
小口径自动机的反后坐装置多采用各种形式的缓冲簧进行缓冲,减小后坐阻力并实现自动机浮动。文中通过理论分析,建立自动机后坐运动方程,在Matlab simulink环境下建模仿真,分别计算2种不同力学性能缓冲簧的后座运动规律,得出在结构尺寸受限的条件下,环形弹簧与螺旋矩形弹簧相比缓冲性能更优。经实弹射击,试验结果与理论计算结果吻合较好,证明本文采用的研究方法正确,建立的仿真模型可用于工程实际。
In order to reduce recoil,all kinds of spring were applied to small caliber automatic cannon usually. Firstly, detached recoil movement equation was established through theory analysis. At Matlab simulink condition, counter recoil efficiency was calculated about two kinds of spring which has different mechanics characteristic. The calculation result indicated that the annular spring′s counter recoil efficiency was better than the screw rectangle spring. The result of calculated by theory model is correct which could be validated by ball firing experiment. At the same time, different recoil movement rules was be give about two kinds of spring.
