脉冲电流发生器 impulse current generator
- 用电容器组脉冲发生器装置作为驱动源,设计4种不同材料、不同尺寸的金属套简,通过调节电容器组的充电电压得到不同的加载电流,研究材料及几何参数、加载脉冲特性对套简屈曲的影响;采用瞬态非线性有限元方法对实验结果进行了数值模拟。
The study of the effect of material properties and dimensions and loading currents on liner buckling, using a capacitor bank as a driver, indicates that the mode number for buckling increases with the ratio of radius to thickness of a liner, and the yield strength to plastic hardening modulus, but keeps invariable with the increase of loading current, and that the magnitude of buckling increases with the loading current.
