The laminate-containment structure is a kind of high-efficiency containment structure, which reduces the eddy current and increases the velocity of the armature. However, the research on the whole launching process of the laminate-containment launcher is rarely mentioned. In order to realize the numerical simulation of the whole launching process of the laminate-containment launcher, a simplified model of the laminate-containment launcher is established, and the electromagnetic–mechanical coupling calculation of the model is carried out by using the finite-element analysis (FEA). In the process of calculation, the pulse power source (PPS) program and electromagnetic field co-simulation are used to realize the field-circuit coupling calculation of the launching process. The movement of the armature during the launching process is realized by an embedded interior ballistic program. This calculation method provides a way to deeply understand the launching process of the laminate-containment launcher.

基于电磁-力耦合模型的层压安全壳发射装置数值模拟


叠层安全壳结构是一种高效的安全壳结构，它可以减少涡流，提高电枢的速度。然而，对于层压安全壳发射装置整个发射过程的研究却很少被提及。为了实现叠层安全壳发射装置整个发射过程的数值模拟，建立了叠层安全壳发射装置的简化模型，并利用有限元对模型进行了电磁-机械耦合计算。分析（有限元分析）。计算过程中采用脉冲电源(PPS)程序和电磁场联合仿真实现发射过程的场路耦合计算。发射过程中电枢的运动是通过嵌入式内弹道程序实现的。该计算方法为深入了解层压安全壳发射装置的发射过程提供了一种途径。
