The Dynamic Characteristics of an Elastic Beam under Moving Oscillating Loads

SHENG Guo gang, ZHAO Bing (Bridge and Structure Eng. Dept., Changsha Comm. Univ., Changsha 410076, China)  
According to the superposition principle of linear system,a new solving method is presented to analyse the 1D elastic distributed system coupled with a moving linear oscillator. The moving oscillating loads in beam is decomposed into the moving constant force loads and the moving inertia loads. Numerical results. testify to the influence of the system parameters on beam deflection, distributed shear force and midspan moment. The method is verified by the numerical results of Pesterev.
