【摘要】：在薄壳的几何方程、物理方程、运动方程和电动力学方程基础上,建立了载流柱壳热磁弹性耦合方程。采用线性化方法,得到了关于热磁弹性问题的线性迭代方程组,整理成含有8个基本未知函数的标准Cauchy型。考虑电磁场的焦耳热效应,引入热平衡方程及广义Ohm定律,得到了柱壳的温度场,并且推导得到了温度场积分特征值。讨论了载流悬臂柱壳应力、温度及变形随外加电磁参量的变化规律,并通过实例证实了可以通过改变电、磁、力场的参数来实现对板壳的应力、应变、温度的控制。
[Abstract]:On the basis of the geometric equation, physical equation, motion equation and electrodynamic equation of thin shell, the thermal magnetoelastic coupling equation of the carrying cylinder shell is established. By using the linearization method, the linear iterative equations on the thermal magnetoelastic problem are obtained, and the standard Cauchy type with 8 basic unknown functions is formed. Considering the Joule heating effect of electromagnetic field and introducing the heat balance equation and generalized Ohm law, the temperature field of cylindrical shell is obtained, and the integral eigenvalue of temperature field is derived. The variation law of stress, temperature and deformation with the external electromagnetic parameters of the cantilever cantilever shell is discussed, and an example is given to prove that the stress, strain and temperature control of plate and shell can be realized by changing the parameters of electric, magnetic and force fields.
