A bogie bogie for testing and testing method

Abstract

The invention discloses a Bo axle bogie for testing and a testing method, comprising a first side beam and a second side beam arranged in parallel, and a parallel arrangement between the first side beam and the second side beam The front end beam, the middle beam and the traction beam are provided on the traction beam, and an end traction seat for connecting the end of the vehicle body is provided, and the end traction seat is detachably connected with the end of the vehicle body through a first traction assembly mechanism; The middle cross member is provided with a middle traction seat for connecting the end of the vehicle body, and the middle traction seat is detachably connected with the end of the vehicle body through a second traction assembly mechanism. The Bo axle bogie for testing and the testing method disclosed in the present invention can carry out bogie tests of different structures, increase the combination of tests, find parameters under a better structure, and greatly save the time required for parameter or structure adjustment. Time, labor and cost required.

Description

technical field [0001] The invention relates to the technical field of production and design of Bo-axle locomotives, in particular to a Bo-axle bogie for testing and a test method. Background technique [0002] With the increase of the speed of rail vehicles, the dynamic performance of locomotives faces a great challenge, especially the lateral dynamics problems of Bo-axle locomotives when the speed is greater than 160km / h. The bogie parameters are the fundamental factors that affect the dynamic performance of the vehicle. In order to verify the dynamic performance of the Bo-axle locomotive, rolling vibration tests or dynamic tests are generally performed to verify whether the dynamic performance of the locomotive meets the requirements. However, there are many parameters in the bogie that affect the dynamic performance of the locomotive. Therefore, the test under high-speed conditions is often faced with various parameter combinations. The parameters of the bogie need to be...

Problems solved by technology

However, there are many parameters in the bogie that affect the dynamic performance of the locomotive. Therefore, the test under high-speed conditions often faces the situation of various parameter combinations. It is necessary to adjust the parameters of the bogie at any time, or sometimes even change the parts of the bogie. Bogie layout

However, it is still possible to simply adjust the internal parameters of the existing bogie without changing the size of the interface when adjusting the damping of the shock absorber. Complex, often need to replace the interface of the frame and key components, and sometimes even cut or weld at the test site to replace the experimental plan, but on-site cutting or welding often involves the protection of key components, the disassembly of components, etc., the The workload is huge and the on-site construction is difficult

[0003] Existing tests to verify the dynamic performance of bogies often only adjust the suspension parameters under the condition that the installation interface and position remain unchanged, such as adjusting the damping of the shock absorber and the shaft Under the condition that the size of the rubber joint of the box tie rod remains unchanged, the stiffness of the rubber joint is adjusted, but this kind of test can only be carried out under the existing structural conditions, only the parameters of the inherent structure are adjusted, and no different structures are tested. The modification of some of the schemes requires dismantling the car body and the bogie or dismantling the wheel set driving device. This method cannot adjust the structure of the bogie. In addition, the workload of testing different schemes during the test is huge. Replacement of parts and schemes The cycle is longer and the test cost is greatly increased
