The invention belongs to the technical field of a track vehicle, relates to a movement platform for a vehicle-end relation detection test of a track vehicle and specifically relates to a variable aluminum section vehicle-end motion platform. The variable aluminum section vehicle-end motion platform comprises a track vehicle bogie double-fix-freedom movement test platform, a cast iron T-shaped groove platform, a hitch support upright column force measuring platform, a crossbeam pipe tile-pinching support seat and a vehicle-end counterforce architecture. The cast iron T-shaped groove platform is fixed on the track vehicle bogie double-fix-freedom movement test platform, the hitch support upright column force measuring platform and the vehicle-end support counter architecture are fixed on the architecture cast iron T-shaped groove platform, the bottom surface of the crossbeam pipe tile-pinching support seat is fixed above the hitch support upright column force measuring platform, and one side of the crossbeam pipe tile-pinching support seat is fixed on the vehicle-end support counter architecture. According to the invention, the requirements for installation positions and test precision of a conventional track vehicle vehicle-end relation test can be satisfied, and an installation scheme is provided for reproduction of research on a vehicle-end relation in actual operation of a track vehicle to the maximum degree.
