Problems solved by technology

The disadvantage of using the circular track method is that it needs to build a test line, which takes up a lot of space, and it is very inconvenient or even impossible to detect some dynamic parameters of the running train.
But the existing fixed test bench, on the one hand, has a complex structure and is difficult to control; on the other hand, only a few working conditions can be simulated on the same test bench

specific Embodiment approach

[0038] Fig. 1, Fig. 2 and Fig. 5 show that a kind of embodiment of the present invention is:

[0039] A railway locomotive vehicle operation simulation test bench is composed of several test units, and the specific structure of each test unit is:

[0040] The driving mechanism is connected with the right roller shaft 9b through the cardan shaft 7, and the left roller shaft 9a is connected with the right roller shaft 9b through a floating coupling 22; or the left roller shaft 9a is connected with the differential transmission mechanism of the driving mechanism; The rollers 8a, 8b are installed on the left and right roller shafts 9a, 9b respectively.

[0041] Left and right roller shafts 9a, 9b are supported on left and right U-shaped frames 12a, 12b by bearings 13 respectively; Right roller seat 14a, 14b inner wall; Left and right roller seat 14a, 14b are all installed on the base 17.

[0042] The bottoms of the left and right U-shaped frames 12a, 12b are connected to the bas...

Embodiment 2

[0052] Fig. 3, Fig. 4 and Fig. 5 show that this example is basically the same as embodiment one, and the difference is to remove the floating coupling (22) between the left roller shaft (9a) and the right roller shaft (9b). Instead, the left roller shaft 9a is connected to the differential transmission mechanism of the drive mechanism; the drive mechanism is composed of: the motor 1 is connected to the synchronous shunt gear box 2', and the synchronous shunt gear box 2' is directly output in the same direction as the motor 1 shaft The end is connected with the right roller shaft 9b through the cardan shaft 7; the synchronous output end perpendicular to the direction of the motor shaft is docked with the synchronous output end of the synchronous shunt gearbox 2' of the adjacent test unit, and the vertical output end perpendicular to the direction of the motor shaft It is connected with the left roller shaft 9a through a differential transmission mechanism. The composition of th...

Abstract

The railway vehicle running simulation test bench comprises several testing units with each composed of drive mechanism connected with left and right rolling wheel supported on the left and right U shape frame that installed on the inner wall of the left and right rolling wheel base through the vertical linear bearing of the side wall, with the right and left rolling wheel installed on the base, left and right U shape frame's bottom connected to the base through the vertical hydraulic vibrator, outer ends of the right and left rolling shafts connected with the horizontal hydraulic vibrator that fastened on the base, the right and left rolling base installed on the base through revolution axis and connected with their own revolution vibrator. It can simulate the running of vehicles on the railway with all kinds of uneven road surface.

Description

technical field [0001] The invention relates to a railway locomotive vehicle running simulation test platform. Background technique [0002] The dynamic performance of railway rolling stock is the most important factor that directly affects the quality of train operation (including safety and reliability, fast and convenient, high efficiency and energy saving, stability and comfort, etc.). Therefore, it is necessary to conduct operational test research on the dynamic performance of rolling stock. [0003] The operating conditions of trains running on actual lines are extremely complex and changeable. To test the dynamic performance of the railway rolling stock, it is necessary to test the dynamic performance of the rolling stock under various working conditions. Specifically, it refers to testing the dynamic performance under the following working conditions: 1. The forward motion of the train, that is, the scroll. 2. Line irregularities caused by errors caused by rail pr...
