电磁冲击压制技术被广泛用于粉末压制、板坯成形等领域,回路电流作为冲击压制驱动源部分,是后续加载驱动的关键因素。文中采用ANSYS多物理场并结合理论计算对放电回路影响因素进行系统分析,探讨了线圈匝数、电压、电容对回路电流的影响规律及各参数对成形效率的影响。结果表明充电电压与回路电流峰值、加载速率成正比,加大充电电压是提高成形效率最直接方法;线圈电阻主要影响电流峰值,与电路加载时间成反比,电感主要影响加载电流加载速率,降低电阻、电感有利于提高成形效率。
Electromagnetic impact suppression technology is widely used in the fields of powder compacting and slab forming, and the loop current is the driving source of impact suppression, which is the key factor of subsequent load driving. In this paper, ANSYS multiphysics and theoretical calculations are used to systematically analyze the influencing factors of discharge loop, and the influence law of coil turns, voltage and capacitance on loop current and the influence of each parameter on forming efficiency are discussed. The results show that the charging voltage is proportional to the peak current and the loading rate. The most direct method to increase the forming efficiency is to increase the charging voltage. The winding resistance mainly affects the current peak, which is inversely proportional to the loading time of the circuit. The inductance mainly affects the loading current loading rate and the resistance , Inductance helps to improve the forming efficiency.
