Abstract
The present invention discloses a simulated loading method and an apparatus for moving load of a wheel axle in rail transportation. Multiple actuators are arranged right above rail sleepers along rail direction. The two continuous rails are connected to the rail sleepers via fastening systems and are cut into discrete independent rail segments right above the rail sleeper. The anti-drop member satisfies the applications of compression and uplift force of the actuator. The input load of each actuator is obtained from the load-time history of a single fastening system under moving load of a wheel axle according to a train-rail-subgrade theory model, and adjacent actuators perform dynamic excitation in turn with a same time interval to achieve simulation of moving load of a wheel axle under different speed. This invention provides a reliable and convenient loading platform for experimental study of the rail transportation.
