摘要:

电磁轨道发射装置作为一种新型发射装置,其身管结构与传统武器系统的身管有本质不同,电磁轨道发射装置身管采用复合材料,內膛结构形状变化多样。壳体刚度和强度满足电磁发射要求是电磁轨道发射装置身管结构研究的关键,轨道支撑材料特性及轨道支撑方式是身管性能的重要保障。以50 mm口径电磁发射装置为例,论述了身管材料特性,采用ansys仿真方法,对发射装置刚度和强度仿真分析,身管的上下扩张量小于0.1 mm。通过靶场实证,轨道间的间距变化在0.1 mm以内,力学仿真结果正确。采用钢壳体,T3铜轨道,陶瓷95和G10为材料的发射装置满足电磁发射的刚度和强度要求。

Abstract: As a new type of launch device, electromagnetic rail launcher’s tube structure is constitutionally different with the tube of traditional weapons systems. Electromagnetic rail launcher tube uses composite materials, and the bore structure shape varies. The key of studying electromagnetic rail launcher tube structure is that shell stiffness and strength meet the requirements of electromagnetic emission, and the characteristics of rail support material and the way of rail support are important guarantees of the body tube performance. In the case of 50 mm diameter electromagnetic launcher, this paper discusses the tube material properties, and presents a simulated analysis on stiffness and strength of launcher using ansys simulation method. The expansion amount of body tube is less than 0.1 mm, and using the methods of range, spacing between orbits changes within 0.1 mm; mechanics simulation result is correct. The launcher device of ceramic 95 and G10 satisfies the requirement of stiffness and strength of the electromagnetic launch using steel shell and T3 copper track.
