摘　　要：以增强型电磁轨道炮为研究对象,利用Ansoft Maxwell和ANSYS Workbench软件建立了轨道炮的电磁结构耦合有限元模型,通过Ansoft Maxwell电磁场有限元分析得到了电枢和导轨的电磁力分布情况,把电磁力作为载荷导入ANSYS Workbench中,对轨道炮的主体结构进行了动力学分析,得到结构的等效应力和变形分布情况。基于正交试验优化方法,对轨道炮的结构关键设计参数进行了优化设计,使优化后结构的强度和刚度满足实际需求。The paper focused on the augmented electromagnetic railgun. The electromagnetic structural coupling model of railgun was established using the software of Ansoft Maxwell and ANSYS Workbench. The electromagnetic field finite element analysis was performed by Ansoft Maxwell, and the magnetic force distribution of armature and rail was obtained. Electromag- netic force was imported into ANSYS Workbench as load for the dynamic analysis of railgun main structure. And the structural equivalent stress and deformation distribution were obtained. Based on the orthogonal test optimal method, the optimal design on the key structural parameters was carried out to make the strength and stiffness of the optimized railgun meet the practical re- quirement.
