Description

High-speed train suspension bogie traction drive system reliability test bench

technical field

The utility model relates to a test device for railway high-speed trains, more specifically, the utility model relates to a high-speed train frame suspension bogie traction transmission system reliability test bench under the load condition of simulating high-speed train running.

Background technique

On April 18, 2007, my country successfully implemented the sixth national railway speed-up map adjustment. Harmony CRH series EMUs appeared on Chinese railways for the first time, realizing 250Km/h high-speed operation on existing lines, thus unveiling It marked the prelude to the high-speed development of my country's railways. At present, the maximum speed of the EMUs in operation has reached 350km/h, but with the increase of the speed, the operating conditions of the components of the high-speed train bogie traction drive system have become worse, and the safety and reliability of key components in operation The problem is becoming more and more prominent.

In order to meet the dynamic performance of the train when running at high speed, the high-speed train driving device mostly adopts the structure of body suspension or frame suspension, which reduces the unsprung mass, greatly reduces the impact force of the wheel rail and the high-frequency mechanical vibration force of the motor, and effectively It is beneficial to the high-speed operation of the vehicle. The bogies of CRH1, CRH2, and CRH3 EMUs all adopt frame suspension type, that is, each power bogie includes two sets of traction transmission systems, and the driving device is fixed on the bogie frame directly or through rubber joints. One end of the gearbox is supported on the axle by two bearings, and the other end is connected to the bogie frame by a suspension device. The driving device and the wheel set need to be connected by a gear coupling that can adapt to relative movement in all directions to transmit torque.

The reliability of the traction drive system directly determines the safety, reliability and economy of rolling stock operation. Checking whether its fatigue strength meets the requirements of locomotive operation is of great significance to improving the reliability of rolling stock. However, because the actual working loads that cause fatigue are very complex, the structural design is ever-changing, the engineering properties of actual materials vary widely, and the stress generated by external loads is very sensitive to structures and materials. Therefore, any analysis method and prediction model has limitations, and the fatigue life simulation analysis has not been very accurate so far. However, conducting actual line tests is costly and risky.

Therefore, the research and development structure is simple and reasonable, aiming at the reliability test bench of the traction transmission system under the load condition of the high-speed train suspended traction transmission system commonly used in high-speed trains, so as to quickly expose the design of key components of the traction transmission system, It is an urgent task to eliminate production defects and improve product reliability.

The working principle of the reliability test bench for the suspension bogie traction drive system of high-speed trains:

Before the test, the tested bogie 4 was stopped on the No. 1 entrance track 11 and the No. 2 entrance track 12 . The control jack 44 is driven by the No. 1 steel wire rope 47 and the No. 2 steel wire rope 48 to drive the No. 1 transition stringer 35 and the No. 2 transition stringer 52 in the lifting device 3 to rise vertically until the No. 1 transition stringer 35 and the No. 2 transition stringer The groove bottom surface of 52 is tangent to the wheel rim of the tested bogie 4. Push the tested bogie 4 onto the lifting device 3, and at this time, the four wheel rims positioned on the inside of the wheel set are supported on the grooves of No. 1 transition stringer 35 or No. 2 transition stringer 52. Push the tested bogie 4 to run along the No. 1 transition stringer 35 and the No. 2 transition stringer 52 . When the central axis of the No. 1 wheel pair 74 of the tested bogie 4 is located on the same vertical plane as the No. 1 roller pair of the power transmission assembly 2 and the No. 1 roller shaft 19 in the gear box assembly 13, the two When the central axis of the No. 2 wheel pair 75 is on the same vertical plane as the No. 2 roller pair in the power transmission assembly 2 and the No. 2 roller shaft center axis of the gearbox assembly 15, loosen the jack 44 so that the 1 The No. 2 fixed beam 29 and the No. 2 fixed beam 30 slowly land on the No. 1 fixed support assembly 33 and the No. 2 fixed support assembly 43 respectively, so that the tread surfaces of the four wheels of the tested bogie 4 are respectively supported on the power transmission On No. 1 left roller 16, No. 1 right roller 17, No. 2 left roller 53 and No. 2 right roller 54 in assembly 2. At this time, adjust No. 1 thrust screw assembly 66, No. 2 thrust screw assembly 67, No. 3 thrust screw assembly 68 and No. 4 thrust screw assembly 69 in the bogie positioning device 5, Fix the tested bogie 4.

During the test, the electrical system controls one motor of the tested bogie 4 as a drive motor in a driving state, and the other motor as a load motor in a braking state. The driving motor transmits the power to the No. 1 wheel set 74 through the coupling and the gearbox. The rotation of the No. 1 wheel set 74 drives the No. 1 roller pair in contact with it and the No. 1 left roller 16 and the No. 1 wheel in the gearbox assembly 13. No. 1 right roller 17 rotates, and No. 1 roller shaft 19 fixedly connected with No. 1 left roller 16 and No. 1 right roller 17 transmits power to No. 1 bevel gear shaft 27 at a constant speed, and drives No. 2 roller pair through coupling 14 And the No. 2 bevel gear shaft of gear box assembly 15 rotates, and finally realizes that No. 2 roller pairs and No. 2 left roller 53 and No. 2 right roller 54 in the gear box assembly 15 rotate through the effect of meshing gears. The electrical system controls the load motor to simulate the torque received by the transmission system during the actual running of the vehicle, and applies a resistance torque opposite to the direction of the roller motion to the No. 2 left roller 53 and the No. 2 right roller 54 . Thus, the simulation of the approximate real working conditions of the two sets of traction drive systems in the tested bogie 4 is realized when the actual line is running. The load motor converts the mechanical energy of the system into electrical energy and feeds it back to the DC bus, thus forming an electrical-mechanical power flow closed-loop test system. The tested bogie 4 is tested on the test bench to grasp the performance of the traction drive system and the fatigue life of the components of the drive system.
