Research On Electromagnetic Emission Speed Control Technologyand Equipment Design

The technology of electromagnetic launch is a leap of the propulsion technology field, there are broad prospects for development, so all countries in the world have done a lot of research.Electromagnetic launcher efficiency has been the focus of the study for a long time, in order to solve such problem, the design of a three stage reluctance electromagnetic launch speed control device.This thiese paper the classification and principle of electromagnetic emission device, and select the reluctance electromagnetic emission device as the research project, analysis the working principle and circuit model of reluctance electromagnetic launcher, and through the reluctance electromagnetic launch acceleration mechanism special for establishing a simulation model, design analysis and main parts of research program.The reluctance electromagnetic launcher for the static and dynamic simulation using finite element analysis software MAXWELL, analyzed the projectile initial position, the projectile parameters, the drive coil parameters and driving circuit parameters effect on the system of emission performance, and the system parameter optimization.On the basis of this research, research on a transmitting device level three reluctance electromagnetic simple, aims at the application of photoelectric detection and computer control technology, flexible control to achieve emission rate. The device can also be used as a launching equipment to verify the underwater trajectory velocimetry system is necessary.The experimental results show that:the experimental data and the simulation results, the designed device in the parameter optimization and increase the photoelectric detection device, The efficiency of reluctance electromagnetic emission device can be increased by 60.4% and provides the technical reference for the research of new reluctance electromagnetic launcher.
