1/3 Subharmonic Resonance of The Electro-conductive Beam in Thermal-Magneto-Elasticity Field

摘要：

　　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 Lorentz force and thermal force on the beam are derived.According to the method of multiple scales for nonlinear vibrations the approximation solution of 1/3 subharmonic resonance of the system is obtained.Numerical analysis results show that the amplitude changed with the system parameters.
