The coil electromagnetic gun is affected by the fixed coil,and the launch angle range is insufficient.In response to this problem,a coil electromagnetic gun experimental machine with a STM32F103C8T6 MCU trolley as a carrier and a launch tube length of 20 cm is designed and produced.Theoretical derivation,mechanical design,computer simulation and experimental testing are carried out.Take the electromagnetic railgun as an example to analyze its advantages and disadvantages.Combined with the principles of MCU,circuit analysis and other disciplines,the design idea of using an MCU to carry a coil electromagnetic gun is proposed.The feasibility analysis is carried out by using the theoretical knowledge of physics and mechanical principles,and the actual design scheme of the experimental vehicle and the coil electromagnetic gun is determined.The research results show that the coil electromagnetic gun mounted on the trolley can still ensure relatively good launch stability,and at the same time increase the mobility of the fixed coil electromagnetic gun body,realizing the further application of the small volume coil electromagnetic gun.And the effect of voltage on the aiming of the electromagnetic gun is verified,which is helpful to promote the development of the practical application of electromagnetic launch technology.
