Embodiment

[0034] Please refer to Figure 1~2 , this embodiment provides a new axle fatigue test bench 1000 . The axle fatigue test bench 1000 includes: a base 100 , a base 200 , a track wheel 210 , an experimental wheel set fixture 300 , a first actuator 400 and a second actuator 500 .

[0035] The track wheel 210 is rotatably arranged on the base 200 and is driven by the driver 150. The wheel surface of the track wheel 210 has a mating portion for carrying the tested wheel pair 600 and for cooperating with the tested wheel pair 600. The test wheel set fixture 300 is erected above the base 100 and has a mounting portion for mounting the tested wheel set 600 .

[0036] The first actuator 400 is arranged vertically and above the experimental wheel set holder 300 for applying a vertical load to the tested wheel set 600 mounted on the experimental wheel set holder 300 .

[0037] The base 200 is slidably disposed on the base 100 , and the slidable direction of the base 200 is set along the...

Abstract

The invention discloses a novel axle fatigue testbed, and relates to the technical field of locomotive vehicle testing. The testbed comprises a base, a foundation bed, a rail wheel, an experiment wheel pair fixator, a first actuator and a second actuator, wherein the rail wheel is arranged on the foundation bed; the experiment wheel pair fixator is erected to the base and is used for installing atested wheel pair; the first actuator is arranged along a vertical direction and is used for applying a vertical load to the tested wheel pair; the foundation bed can be arranged on the base in a sliding way, and the slideable direction of the foundation bed is arranged along the axial direction of the spindle of the rail wheel; the second actuator is also arranged along the axial direction of thespindle of the rail wheel; and the first actuator is connected between the base and the foundation bed and is used for applying a lateral load to the tested wheel pair. By use of the testbed, load transfer accuracy is greatly improved, a true load effect can be more accurately reflected, and a fatigue test result is more accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of testing railway locomotives, in particular to a novel axle fatigue test bench. Background technique [0002] The inventors of the present application have found through research that: the existing axle fatigue test bench restricts the degree of freedom of rotation during the measurement process, so that the load transmission does not conform to the actual situation, and does not have the effect of reflecting the real load. [0003] In view of this, this application is proposed. Contents of the invention [0004] The purpose of the present invention is to provide a novel axle fatigue test bench, which greatly improves the accuracy of load transmission, can more accurately reflect the real load effect, and the result of the fatigue test is more accurate and reliable. [0005] Embodiments of the present invention are achieved like this: [0006] A novel axle fatigue test bench includes: a base, a base, a...
