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

[0037] figure 1 , figure 2 and Figure 5 Shown, a kind of specific embodiment of the present invention is:

[0038] A railway locomotive vehicle operation simulation test bench is composed of several test units, and the specific structure of each test unit is:

[0039] The driving mechanism is connected to the right roller shaft 9b through the cardan shaft 7, and the left roller shaft 9a is connected to the right roller shaft 9b through a floating coupling 22; or the left roller shaft 9a is connected to the differential transmission mechanism of the driving mechanism; The right rollers 8a, 8b are installed on the left and right roller shafts 9a, 9b respectively.

[0040] 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.

[0041] The bottoms of the left and right U-shaped frames 12a, 12b are co...

Embodiment 2

[0051] image 3 , Figure 4 and Figure 5 Shown, this embodiment is basically the same as Embodiment 1, except that the floating coupling (22) between the left roller shaft (9a) and the right roller shaft (9b) is removed. 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 t...

Abstract

A railway locomotive vehicle operation simulation test bench is composed of several test units, each test unit has the following structure: the driving mechanism is connected with the left and right rollers, and the left and right rollers are supported on the left and right U-shaped frames; The right U-shaped frame is installed on the inner wall of the left and right roller seats through the vertical linear bearings on the side walls; the left and right roller seats are installed on the base; The exciter is connected to the base; the outer ends of the left and right roller shafts are connected with the transverse hydraulic exciter, and the transverse hydraulic exciter is fixed on the base; the left and right roller seats are respectively installed on the base through slewing bearings , and connected to their respective rotary exciters. The test bench can simulate the movement of rolling stock on the railway line; it can simulate the smooth running state of the vehicle, and it can also simulate the vertical irregularity of the line, the horizontal irregularity, the disturbance of the lateral and horizontal bending, and the disturbance of the vehicle in the curved line environment. state of motion.

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...
