| Abstract: |
| The ground vibrations caused by moving trains have been intensified as the trains run faster.Based on the finite element theory,track dynamics and the Green's functions of foundation soil,an integrated track-soil dynamic interaction model is established.In order to acquire the dynamic equations,in the paper,a static degree-of-freedom(DOF) condensation mode is utilized to eliminate the rotation DOF existed in beam.The stiffness matrix can be determined by aid of the definition of receptance matrix in literature [12] and Hankel Transformation,furthermore,the dynamic responses of system can also be calculated by Newmark method.In the last,the Sweden's X2000 high-speed passenger train is taken as the object,the feasibility of the proposed method is demonstrated by comparing with the experimental data. |
