摘要: 导出了磁场中圆柱薄壳体的磁弹性轴对称振动方程及电磁力和力矩的具体表达式,并分别推得了壳体位子纵向和横向磁场中振动的特征方程。通过算例给出了振动频率和衰减系数随场强的变化曲线,表明适当磁场的通入,可达到控制壳体振动特性的目的。Abstract: The axisymmetric magnetoelastic vibration equations of a thin cylindrical shell in magnetic field are derived. A numerical example is provided in which the effects of magnetic intensity on vibration characteristics are studied.
