摘要
在对机械载荷与非定常电磁场耦合作用下的球台薄壳的应力、位移与电磁场、机械场等关系研究的基础上,建立了载流球台壳的磁弹性基本方程.采用分离变量法,导出了数值计算方程式,并通过具体算例,讨论了电场中电磁量、作用时间等因素与球台壳应力及变形之间的关系.
Based on the research of the relationships between the electro-magnetic field, mechanical load and the stress, the deformation of the thin current-carrying spherical segment shells under the combined action of electro-magnetic field and mechanical load, the nonlinear electro-magnetic kinetic equations of the spherical segment were built in this paper. Using the separated variable method, the mathematical calculated equations were obtained. And in the specific examples, the relationships between the electro-magnetic field, time and the stress, the deformation of the spherical segment shells were studied.
