摘要
为探讨开展电磁炮大脉冲电流旋转连接技术研究的必要性,参照美国"Blitzer"电磁炮的结构形式和参数,构建了防空电磁炮A的几何模型。计算结果表明同轴电缆系统产生的最大阻力矩达到6 026.4 N·m,会对随动系统产生严重干扰,说明开展大脉冲电流旋转连接技术研究是必要的。进一步给出一种采用环形电刷的电磁炮俯仰型旋转电连接装置的方案和工作原理,据此方案研制的试验装置通流能力达到了400 k A。这为采用大脉冲电流旋转连接技术解决电磁炮俯仰供电问题提供了试验依据。
In order to discuss the necessity of the research on the large pulse current rotary joint technology of the electromagnetic gun, referring to the structure and parameters of the USA ＇Blitzer＇ electromagnetic gun, we established the geometric model of air defense electromagnetic gun A. The calculated results show that the maximum torque of the coaxial system is 6 026.4 N·m, this will seriously interfere with the servo system and this shows that it is necessary to research the technology of large pulse current rotary joint. Moreover, we put forward a scheme of structure and working principle of the pitching type rotary joint device with a ring brush for electromagnetic gun.According to this scheme, the current-carrying capacity of the test device will be developed to 400 kA. This can provide the experimental basis for the use of large pulse current rotary joint technology to solve the problem of the electromagnetic gun pitch power supply.
