| Abstract: | The transient dynamic response to an Euler beam rested on the elastic foundation subjected to the transverse dynamic load is studied.In the article,the analytical solution's expression of the driving deformation of beam is derived by using modal superposition method,and the dynamic response characteristic curves of the central deflection of the beam versus the non-dimensional time under the sudden load and step load are plotted. |

| Keywords: | Euler beam elastic foundation modal superposition method transient dynamic response |
