Comprehensive test system for rail vehicle components and complete vehicles

Abstract

The rail vehicle components and the whole vehicle physical comprehensive test system provided by the present invention include: the network test system sends the control command signal to the network bus system; the simulation system establishes the rail vehicle model, calculates the simulation parameter signal information according to the control command signal, and The simulated parameter signal information is sent to the network bus system; the control system calculates the control information according to the simulated parameter signal information, and sends the control information to the network bus; the traction test system distributes the electric braking force according to the control information and the simulated parameter signal information; The dynamic test system distributes the air braking force according to the control information and the simulation parameter signal information; the first data acquisition system collects the data information of the traction test system and the brake test system, and sends them to the simulation system through the network bus system. The invention does not need to be loaded into a vehicle, realizes the electric-pneumatic joint test, reduces time consumption and cost, and improves work efficiency and test reliability.

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...
