Rail vehicle vehicle terminal relation integration testing stand

Abstract

The invention discloses a rail vehicle vehicle terminal relation integration testing stand, comprising a six freedom degree motion platform assembly, a truss vehicle end wall assembly, a simulation vehicle frame and fixed platform assembly and a test assembly. The simulation vehicle frame and fixed platform assembly is provided at the right side of the six freedom degree motion platform assembly, the fixed platform in the simulation vehicle frame and fixed platform assembly and the motion platform of the six freedom degree motion platform assembly share a plane along the symmetric plane of the X shaft direction, and the upper working face of the simulation vehicle frame in the simulation vehicle frame and fixed platform assembly is on the same horizontal plane with the upper working face of the motion platform. The motion terminal truss vehicle end wall assembly of the truss vehicle end wall assembly is fixedly connected to the motion platform and the fixed terminal truss vehicle end wall assembly is fixedly connected to the upper working face of the simulation vehicle frame. The test assembly is located between the simulation vehicle frame and fixed platform assembly and the six freedom degree motion platform assembly and the symmetric plane of the test assembly along the X shaft direction share a same plane with the symmetric plane of the truss vehicle end wall assembly along the X shaft direction.

Description

technical field [0001] The invention relates to a test bench for a rail vehicle, more specifically, the invention relates to a comprehensive test bench for a vehicle-end relationship of a rail vehicle. Background technique [0002] The car end is an indispensable and important device in the composition of rail vehicles, which plays the role of connecting each car and making it pass through various curves and curves smoothly under the drive of the train. The performance of the train end directly affects the operation quality and safety of the EMU (train). The car end relationship test refers to the relative movement and rotation of the parts installed at the end of the car body during the operation of the train due to the relative movement and rotation of the parts of the train body and when passing through the curve. By measuring the displacement and force of the parts To measure the stiffness and damping parameters of the train end, and provide accurate data for the analys...
