The invention discloses a high-speed train large system coupling dynamic simulation platform which adopts a distributed simulation system based on C / S (client / server) mode and comprises a foreground human-computer interaction interface portion and a background distributed based core calculating portion. The background based core calculating module comprises a task scheduling module, a coupling control module, an executor agent module, a vehicular dynamic calculation module, a line dynamic calculation module, a bow net dynamic calculation module, a tractive power supply calculation module and an air dynamic calculation module, and the foreground human-computer interaction interface portion comprises a main control module, a pre-processing module, a calculating resource management module, a calculation monitoring module, a post-processing module and a system management module. The high-speed train large system coupling dynamic simulation platform is supportive of multiple working conditions for simultaneous high speed train large system coupling dynamic simulation, capable of monitoring calculation process in real time, good in expansibility and supportive of heterogeneous exclusive-operation system, and provides a good platform for coupling simulation and operation simulation of a high speed train and a line, a contact network and a power supply system and coupling relation study and performance evaluation of the high speed train and other subsystems.

Description

technical field [0001] The invention relates to simulation control technology, in particular to the technical field of high-speed train large-system coupling simulation platform. Background technique [0002] With the vigorous construction of my country's high-speed rail network, the record of operating speed being refreshed again and again, and the signing of high-speed rail technology export memoranda with Russia, the United States, etc., the operation safety of high-speed trains under the new situation is an urgent and rigid demand. This poses a serious challenge to the safety research of high-speed railway, and also provides an unprecedented opportunity. [0003] The operation of high-speed trains is affected by the conditions of fixed facilities such as lines and catenary, the control of traction power supply and train operation control system, and is also restricted by air disturbance, resistance and noise. Therefore, the relationship between the high-speed EMU and th...

Problems solved by technology

[0004] At present, the dynamics research related to high-speed trains is mainly concentrated on the subsystem level, such as train dynamics, line dynamics, pantograph-catenary dynamics, etc. These subsystem research and computing platforms are generally relatively independent and unsystematic, although some researches have gradually Extending to the dynamics of high-speed train coupling large systems, such as vehicle-line-bridge dynamics research, but these cannot fully meet the current simulation analysis requirements of high-speed train large system coupling dynamics

So far, there is no mature software system at home and abroad that can provide calculation support for the simulation analysis of large-scale high-speed train coupling dynamics.
