摘要

摘要: 针对脉冲大电流放电实验中汇流装置因极强后坐力导致与轨道连接件断裂等问题，从力学特性入手，研究了高通流能力、长寿命、可操作的汇流装置结构。大电流致使汇流装置受到极强后坐力，为了削弱后坐力的影响，对汇流装置与轨道夹角不同的情况进行了几何结构设计和仿真分析。通过受力分析、初速度计算，得到高可靠性、方便操作的汇流装置优化结构，并可在实验室中得到应用。

Abstract: Electromagnetic rail launcher (EMRL) is one of the new propulsor based on impulse discharge with pulsed high current technique. In recent years, the research of EMRL has attracted the attention of domestic and foreign institutions, such as China laboratories, the United States Navy Laboratory, the Franco-German Joint Laboratory, and has made great progress. In order to solve the fracture problem between bus-bar and rail connections caused by strong recoil. In experiments, base on the study of mechanical properties, this paper studies a bus-bar structure with high flow capacity, long life, and operational characteristics. The high current causes the bus-bar to be subjected to a strong recoil, in order to weaken the influence of the recoil, geometric design and simulation analysis are done according to the different angles between the bus-bar and the track. A highly reliable, easy to operate bus-bar optimization structure is obtained through the force analysis and initial velocity calculation. This structure can be used in laboratory.
