Embodiment Construction

[0030] The accompanying drawings show an embodiment of the present invention, and the present invention will be further described below in conjunction with the accompanying drawings.

[0031] A monorail vehicle traction linkage system fatigue test method, the test method is:

[0032]Place the traction link system in a simulated car body and bogie system, install it horizontally on the test platform as a whole, and carry out combined loading on it from the vertical and lateral (horizontal) directions respectively through the loading cylinder and the test fixture , in which the upper ball joints of the four traction rods of the traction linkage system are fixed on the bearing platform of the simulated car body device by bolts, and form a double torsion bar mechanism with a four-link internal force balance. -190mm) to install a hinge device, the hinge device passes through 4 guide seats in parallel and connects with the vertical loading cylinder through the loading beam, and the ...

Abstract

Disclosed are a fatigue testing device and a fatigue testing method for a traction connecting rod system of a single-rail cart. The fatigue testing method for the traction connecting rod system of the single-rail cart includes disposing the traction connecting rod system on a simulated cart body and a bogie system and mounting the same on a testing platform horizontally integrally, jointly loading on the traction connecting rod system from the vertical and lateral (horizontal) direction via a loading oil cylinder and a testing tooling, fixing ball hinges at the upper ends of four traction rods of the traction connecting rod system on a carrying platform of the simulated cart body via bolts to form a double-torsion rod mechanism with internal force of four connecting rods balanced, and mounting a hinge device at a position deviated from the center of the carrying platform by a certain distance, wherein the hinge device penetrates through four guide seats in a parallel manner and is connected with a vertical loading oil cylinder through a loading crossbeam, and the vertical loading oil cylinder applies traction force on the upper group and the lower group of traction rods in an eccentric loading manner, so that deviation angle generated makes runout actions around a rotary shaft via the hinge device, runout loading is eliminated, and accordingly, vertical loading on the traction connecting rod system is realized.

Description

technical field [0001] The invention relates to a test device and test method for railway components, in particular to a fatigue test device and test method for a monorail traction link system, the device and test method are monorail traction link systems and related systems A set of test devices and test methods are provided for the fatigue test of components, which belongs to the field of test technical scheme and test equipment. Background technique [0002] The traction link system is an important traction and vibration-damping component in the bogie of a monorail car. It is a system component composed of metal components and rubber elastic components. Composed of rods and hydraulic springs, the main function is to transmit the traction force of the monorail car body relative to the bogie and ease the centrifugal force and yaw displacement generated when the vehicle passes through the curve. It has the advantages of good vibration reduction effect and convenient maintena...
