摘要为适应未来战争需要，探索新型发射技术。本文根据电磁原理设计了一种发射铁磁性枪弹的电磁枪。分别从理论分析、总体方案设计和实验测试三个方面开展研究工作。首先，介绍了三种电磁发射技术的原理及特点，并着重对线圈式电磁感应相关理论和关键技术进行了综述。然后，采用UG软件建立了电磁枪的三文总体结构模型，全枪采用无拖式布局，8级加速线圈作为枪管，依靠电磁铁的往复运动进行供弹。最后，采用一级线圈研究了电压和电流变化对弹体侵彻深度的影响。实验表明，侵彻深度随电压和电流的增高显著增加。当电压为30V、电流为6A时对橡皮泥的侵彻深度可达8mm。31912

Title Design and analysis of the gauss rifle
Abstract
In order to meet the future needs of war, exploring new emission technology. Based on the principle of electromagnetic design of a ferromagnetic bullet electromagnetic emission gun. Respectively, from the theoretical analysis, to carry out research work overall program design and experimental tests of the three aspects. Firstly, the principle and characteristics of three types of electromagnetic launch technology, and focus on the theory of electromagnetic induction coil and key technologies are reviewed. Then, using UG software to build a three-dimensional model of the overall structure of the electromagnetic gun the whole gun-free drag-style layout, speed up coil 8 as a barrel, the reciprocating motion solenoids were relying for the bomb. Finally, research the primary winding voltage and current changes in projectile penetrating effect depth. Experimental results show a significant increase in the penetration depth with increasing voltage and current. When the voltage is 30V, current is 6A for plasticine penetration depth of up to 8mm.
