为了获得内边界固定的环形导电薄板在均布力与横向磁场作用下的变形问题的数值解,通过建立运动方程、变形方程、电动力学方程和洛仑兹力方程,运用迭代法得出了载流板壳的非线性磁弹性的计算方法和结果,以及机械场、电磁场对铁质变厚度圆板各力学参量的影响程度.

Analyses on the Distortion and Internal Force of Varying-thickness Round Plates with Fixed Constraint of Inner Edges in Electromagnetic Field

For obtaining the numeral solutions of round elastic plates in axisymmetrical deformation with varying-thickness in nonlinear deformation in the unsteady electromagnetic field and mechanical field,by establishing the equations of motion,the equations of distortion,the equations of Lorentz force,the equations of electronic dynamic mechenical,and adopting iterative method,we gained the nonlinear magneto-elastic calculation method and outcome of current-carrying shell,and gained the influencing degree toward mechanical parameter of varying thickness round ferreous plates in the electromagnetic field and mechanical field.
