Abstract

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.
