Problems solved by technology

In actual work, the elastic side bearing is subjected to vertical dynamic load and friction along the longitudinal direction of the vehicle, but the current test device for testing the elastic side bearing separates the vertical load test and the longitudinal load test, which is obviously different from the actual elastic side bearing. The motion conditions are inconsistent, so there is a certain deviation in the test results

Abstract

The invention discloses an elastic side bearing fatigue test device. The elastic side bearing fatigue test device comprises a side bearing seat, a base composition, a horizontally arranged connecting beam, a horizontal loading device and a vertical loading device, wherein the side bearing seat is used for placing a side bearing; the base composition is provided with a supporting table which supports the side bearing; one end of the connecting beam is fixedly connected to the side bearing while the other end of the connecting arm is hinged to a positioning pin; the positioning pin is fixedly arranged a positioning pin boss which is far from the base composition at a certain distance; the horizontal loading device is used for applying a horizontal load to the side bearing; and the vertical loading device is arranged on a side bearing wearing plate of the elastic side bearing for applying a vertical load to the elastic side bearing. According to the elastic side bearing fatigue test device and method, the actual applying work condition of the elastic side bearing can be simulated, so that the reliability of an elastic side bearing fatigue test result is improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to an elastic side bearing fatigue test device and method. Background technique [0002] Rail vehicles generally include car body, bogie, brake device, coupler buffer device and other parts. Among them, the function of the bogie is to support the car body, guide the vehicle to run along the track, and bear various loads from the car body and the line. The car body and the bogie are connected as a whole through the center plate and side bearings. [0003] Among them, the elastic side bearing is a commonly used side bearing, which has the function of preventing the side sway angle of the car body from being too large, and at the same time provides a stable turning resistance moment between the car body and the bogie, improving the stability of the vehicle. [0004] Before the actual application of the elastic side bearing, its fatigue reliability needs to be verified, so it ne...
