Railway vehicle part and whole vehicle physical comprehensive test system

Abstract

The invention provides a railway vehicle part and whole vehicle physical comprehensive test system. The system comprises a network test system which sends a control instruction signal to a network bussystem; a simulation system which establishes a rail vehicle model, calculates to obtain analog parameter signal information according to the control instruction signal, and sends the analog parameter signal information to the network bus system; a control system which calculates according to the analog parameter signal information to obtain control information, and sends the control informationto the network bus; a traction test system which distributes electric braking force according to the control information and the simulation parameter signal information; a brake test system which distributes air brake force according to the control information and the simulation parameter signal information; and a first data acquisition system which acquires data information of the traction test system and the brake test system and sends the data information to the simulation system through the network bus system. According to the system, loading is not needed, the electro-pneumatic combined test is realized, the time consumption and the cost are reduced, and the working efficiency and the test reliability are improved.

Description

technical field [0001] The invention relates to the technical field of traction braking control, in particular to a comprehensive test system for rail vehicle components and complete vehicles. Background technique [0002] During the R&D and delivery of rail vehicles, individual and complete vehicle R&D tests and type tests of key systems such as traction, braking, auxiliary, and network systems are required. The test items are numerous, and data collection and processing are complex and highly specialized. At present, the various systems of domestic rail vehicles are still carried out by the sub-system suppliers using the internal parameters or test equipment of their respective systems. The data of different systems cannot be accurately synchronized, and mutual cooperation tests have not been carried out. , It takes a lot of time to adjust the relationship between each system to achieve a smooth transition after loading the vehicle. At the same time, the fault of the vehic...
