摘要
采用瞬态非线性有限元方法对电磁内爆套筒屈曲进行了数值模拟研究。介绍了瞬态非线性有限元方法的基本原理、电磁内爆套筒模拟的基本方法及对实验的模拟结果。通过分析比较认为,建立的数值模拟方法较好地反映了实验结果,可以作为研究分析电磁内爆套筒屈曲的基本方法之一。
With the aid of instant nonlinear finite element method, a numerical simulation to dynamic buckling of the implosion liner driven by magnetic pressure has been carried out. The principle of the method and the results of simulation has been introduced and discussed. The comparison of simulation results with experimental ones indicated that the simulation method established by this paper are validated and can be used as a useful tool for the study of liner implosion buckling.
