Abstract
The present invention discloses a simulated loading method and an apparatus for moving load of a whole train in rail transportation. Multiple actuators are arranged above rail sleepers along rail direction. The rail is cut into separate rail segments, which are connected to rail sleepers via fastening systems. Based on a verified train-rail-subgrade theory model, the distribution of fastener force under the movement of a train bogie can be obtained. A simplified expression of this solution can be acquired by Gauss function fitting considering the train axle load, which is used as the input load of actuators. Each actuator performs the same dynamic excitation sequentially with a time interval along the train moving direction. Therefore, moving load of different vehicle types at different train speeds can be simulated. The present invention provides a reliable and convenient test method and an apparatus for research of developing infrastructures of rail transportation.
