Embodiment Construction

[0026] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0027] Such as figure 1 As shown, a high-speed EMU braking test system includes a test console 1 and a relay box 2. Among them, the test console 1 is used to simulate various speed signals, various vehicle air spring load signals and regenerative braking simulation signals, and to collect and analyze braking data. The relay box 2 is used to collect and transmit information between the tested vehicle 3 and the test console 1 , and each tested vehicle 3 is equipped with at least one relay box 2 .

[0028] Each EMU consists of eight carriages. For the convenience of testing, two test consoles 1 are generally used, one as the front test console and the other as the rear test console. The two test consoles 1 are connected via Ethernet linkage control. In the 8 cars of the EMU, a test console 1 (that is, the front test console) is generally arrange...

Abstract

The invention relates to a method and a system for testing the brake of a high-speed motor train unit. The method comprises the following steps of: in a stationary state of a motor train unit, simulating various speed signals, train air spring load signals and regeneration brake analog signals by utilizing the testing system; after various analog signals are received by the motor train unit, applying a brake action by a train brake system, and outputting brake information; and acquiring and analyzing brake information data and judging whether the design requirements for various performance indexes of the brake system are met. According to the method and the system, in the stationary state of the motor train unit, various performance indexes of the motor train unit brake system can be comprehensively and effectively tested through simulating the train speed signals and the train air spring load signals, wherein the performance indexes comprise brake response time of the motor train unit, logic motions of an anti-slip system, regenerated brake feedback, air brake, sequential coordination control of regenerated brake, and the like, so that intensive study of complete train debugging key technologies of the motor train unit is realized so as to achieve the purpose of all-around high-precision analogue simulation of the test of the brake system.

Description

technical field [0001] The invention relates to a method and a system for testing the performance of a train set, in particular to a test method and a test system for a brake system of a train set, and belongs to the technical field of performance tests of rail vehicles. Background technique [0002] With the continuous improvement of the running speed of the EMU, the performance of the braking system of the EMU is related to the safety and reliability of the operation of the EMU. Therefore, the performance test and system debugging of the EMU braking system are particularly important. [0003] In the past, rail vehicles only used vehicle control commands to confirm the braking system, which could not verify the function of the vehicle in a dynamic state, resulting in a small test area and disconnected from actual operation, which could not meet the current high-speed EMU test and system debugging. Require. Contents of the invention [0004] The main purpose of the presen...
