摘要
The paper herein proposes a new method to study the response of a discretely supported rail, as a. result of moving loads. The method bases on the rail Green's functions and the basic features of the ballasted track - namely to be a periodic and damped structure - and it takes into account an arbitrary number of moving loads travelling along the rail. Numerical simulations focus on the case of two moving harmonic loads and feature significant coupling between the loading points.
