Abstract

The invention discloses a maglev bogie fatigue test loading device, which comprises a testing platform base, a support base, an air spring support, a loading power part used for loading a bogie according to a requirement, and a load transfer device arranged between the loading power part and the bogie, wherein the testing platform base is fixed on the ground; the support base is fixed on the testing platform base; the lower end of the air spring support is pivoted with the support base through a pin roll; the extension direction of the axis of the pin roll is parallel to the front-back direction of the bogie; the upper end of the air spring support is connected with an air spring connecting seat of the bogie; and a horizontal pull rod connecting seat is arranged on the side of the supportbase, and is connected with a side-rolling resistant beam of the bogie through a horizontal pull rod. The maglev bogie fatigue test loading device can well simulate the fatigue load on the bogie, andaccurately test the fatigue property of the bogie.

Description

technical field [0001] The invention relates to the technical field of maglev train traffic, in particular to a fatigue test loading device for a bogie of a maglev train. Background technique [0002] The maglev train is a high-tech transportation tool that utilizes the attractive and repulsive forces of the magnetic poles. Because of its fast running speed, smooth and comfortable operation, easy control, low noise, high environmental protection performance, low operation, maintenance and energy consumption costs, etc. Advantages are increasingly valued by countries all over the world. [0003] The bogie of medium and low-speed maglev train is the most critical part of the whole vehicle. It supports the weight of the whole vehicle, transmits the traction force and braking force. The finite element analysis and fatigue load test were carried out on it. [0004] Please refer to figure 1 and figure 2 , figure 1 It is a structural schematic diagram of a typical medium-low ...
