Embodiment Construction

[0025] After the railway vehicle bogie referred to in the present invention is assembled and completed, the basic performance parameters of the bogie must be tested to ensure that the performance parameters of each bogie meet the technical requirements. The detection platform must be located at the end of the bogie assembly production line, and at the same time, it must meet the on-line detection of the bogie assembly production line's takt (about 15 minutes).

[0026] The invention is based on:

[0027] (1) The comprehensive testing platform must simulate the online testing environment such as the loading of the rail vehicle body bolster, the rotation of the bogie and the traverse of the wheel set;

[0028] (2) The railway vehicle bogies tested are two-axle bogies of various types with axle loads ranging from 21T to 32.5T. 840~915mm;

[0029] (3) There are nine items to be detected by the comprehensive inspection platform, among which: the important items are the height of ...

Abstract

The invention provides a bogie performance parameter combined test stand of a rail vehicle. The test stand comprises a mechanical analog detection device and a test signal transmitting and processing system; the mechanical analog detection device mainly comprises a frame, a shifting platform, a loading beam, a vertical loading actuator, a horizontal loading actuator, a wheel pair clamping actuator and a track; and the test signal transmitting and processing system contains an industrial control computer, a laser distance meter, a load sensor, a transmitting channel of the load sensor used for generating signals and a data processing software. By using the test stand of the invention, the simulation of the loading of the vehicle body corbel of the overall bogie of the rail vehicle,, the rotation of the bogie and the traverse movement of the wheel pair can be realized; the installed test signal transmitting and processing system can realize fast, accurate and comprehensive detections of various items and ensure the reliability of the dynamic performance parameters of the bogie; and the safety performance of the rail vehicle can be increased and the requirements of the related rules of the ministry of railway can be satisfied.

Description

technical field [0001] The invention relates to detection equipment for vehicle performance parameters, in particular to a comprehensive detection platform for rail vehicle bogie performance parameters. Background technique [0002] The determination of the performance parameters of the rail vehicle bogie is an important means to ensure that the dynamic performance of the vehicle meets the specified requirements. For a long time, the determination of the performance parameters of the manufactured rail vehicle bogie can only be done by separating its main components and placing them one by one on different test benches in the laboratory for testing. This test method, due to the existence of factors such as the error of the processing size of each component and the tolerance during assembly, inevitably results in the discreteness of the performance parameters of the rail vehicle bogie. This discretization has a great influence on the dynamic performance of the vehicle. That ...
