螺栓紧固式轨道炮后坐规律研究
|
摘要
轨道炮两条平行导轨在发射过程中受到向外侧的扩张力,为了约束导轨扩张,采用螺栓紧固形式的外层封装结构。为研究螺栓紧固式轨道炮的后坐规律,建立发射系统模型,对发射过程中后坐部分的受力进行分析,并建立后坐复进运动微分方程。结合两种反后坐装置方案,对螺栓紧固式轨道炮的后坐规律进行了仿真计算和试验测试。仿真计算结果与试验结果表明:与常规火炮相比,螺栓紧固式轨道炮具有后坐行程短、后坐速度低的特点;在螺栓紧固式轨道炮上使用的节制杆式驻退机需要具有更小的流液孔面积,以提高驻退机力。
The two parallel rails of railgun are subjected to lateral tension during launching. A bolt-fastened encapsulation structure was adopted to restrain the expansion of the rails. For the sake of research on recoil law of bolt-fastened railgun,a launch system model is established,the force acting on the recoils in launching process is analyzed,and a differential equation of recoil and counterrecoil motion is established. For two kinds of counterrecoil mechanison schemes,the recoil of bolt-fastened railgun was simulated and tested. The simulated and experimental results were compared and analyzed. It is concluded that,compared with the conventional gun,the bolt-fastened railgun has the characteristics of short recoil stroke and low recoil velocity,and because of the low recoil velocity,the throttling bar recoil brake used in bolt-fastened railgun needs a smaller flow hole area to improve the recoil force.
