摘要
在弹性梁与磁弹性力学理论的基础上,应用动力学方法建立电磁场和温度场耦合作用下的载流梁的非线性热磁弹性耦合振动方程。应用Galerkin法导出了系统受电磁力和热力共同作用的非线性振动微分方程组。通过数值计算,给出了不同系统参数下的系统振动的时程图和相图。
Based on the electro magneto elastic theory and the theory of the bending vibration of the electric beam, nonlinear vibration equation of current carrying beam in thermal magneto elasticity field is studied. The Electromagnetic force and thermal force on the beam are derived. In addition, according to the Galerkin Method, the corresponding nonlinear vibrations differential equations are derived. Through the numerical calculation, the time history response plots and the phase charts are obtained with different system parameters.
