摘要
通过构建用高能率加载装置与平板线圈构成的强冲击载荷压制系统,分析了物理模型的强冲击电流动态响应过程,并建立了等效电路的二阶系统模型,提出产生电磁冲击力的冲击电流就是该系统的脉冲响应。系统脉冲响应函数的理论分析和数值模拟表明,降低阻尼比、减少回路电感和增大电容有益于提高电磁冲击力的强度和效率。
The high-impact compaction system consists of the device of high energy rate load system and flat coil. Through analysis the physical model dynamic response of .high pulse current in physical model, established the second-order systems of equivalent circuit,and suggested that electromagnetic force causing by impacting current is pulse response of the system. By studying the function of impulse response and numerical simulation, the results show that the reduced damping factor, larger capacitance and decreasing circuit inductance are beneficial to increase the intensity and efficiency of electromagnetic impact force.
