Abstract

The invention discloses a motor train unit bogie stability testing device and testing method, and the device comprises a pedestal, wherein the top of the pedestal is provided with a pair of parallel first collision walls, the top of the pedestal is also provided with a first chute, and the first chute is located between the two first collision walls; a straight line where the length direction of the first sliding groove is located is perpendicular to the plane where the first collision walls are located, a first sliding block is arranged in the first sliding groove, pressure rods are arrangedon the side faces, opposite to the two first collision walls, of the first sliding block respectively, and first pressure sensors are arranged at the ends, corresponding to the pressure rods, of the two first collision walls respectively. By means of the technical scheme, the method has the advantages of being small in test result deviation, high in test efficiency and easy to operate.

Description

technical field [0001] The invention relates to the field of bogies, in particular to a stability testing device and a testing method for a bogie of an EMU. Background technique [0002] The bogie is one of the most important components in the rail vehicle structure and plays a very important role. It is guaranteed that under normal operating conditions, the car body can be reliably seated on the bogie, and the rolling of the wheels along the rail is converted into translational motion of the car body running along the line through the bearing device. Support the car body, bear and transmit various loads and forces from the car body to the wheels or from the wheel rail to the car body, and distribute the axle load evenly. To ensure the safe operation of the vehicle, it can flexibly run along the straight line and pass the curve smoothly. The structure of the bogie should facilitate the installation of the spring damping device, so that it has good damping characteristics, ...
