| Abstract: | Study on the primary resonance of a beam externally excited on the Winkler foundation in a temperature field is carried out.Applying the elastic theory and Galerkin's method,the nonlinear dynamical equation of a beam externally excited on the Winkler foundation in a temperature field is established.By means of the method of multiple scales the approximate solution of the primary resonance of a system is obtained.Numerical analysis of the influence of all kinds of parameters on the system is also carried out. |

| Keywords: | Winkler foundation temperature field the method of multiple scales nonlinear vibration |
