Abstract

The invention relates to a dynamics coupling simulation method of a high-speed train system. Multidirectional coupling control of collaborative simulation based on simulation step length stages can be achieved under the interaction relationship among multiple device parameters and multiple fields based on interfaces and under the environment of parameter control. The method is used for collaborating all sub-systems of different simulation step lengths to achieve coupling control simulation. Influences in relative fields such as a train dynamics, bow net dynamics, an air dynamics, a car-line coupling dynamics and a car-air coupling dynamics are considered completely, coupling calculation among fields of high-speed train-line-bow net-pneumatic power-traction power supply based on integral step length stages can be achieved, and mutual influences of high-speed trains and surrounding environment such as rail lines, contact nets and flows are considered completely.

Description

technical field [0001] The invention relates to simulation control, in particular to the technical field of coupling control simulation for multi-variable subsystems. Background technique [0002] In a high-speed operating environment, the operational safety of high-speed trains is one of the main objectives that need to be paid attention to, which in turn depends on the performance of high-speed trains themselves determined by the dynamics of high-speed trains. The operating environment of high-speed trains is complex, and the dynamic performance is affected by the complex coupling effects of track lines, catenary, and surrounding airflow. However, in the existing high-speed railway research system, researchers mainly carry out the simulation research of single subsystem or local coupling. The research of single subsystem such as high-speed train dynamics, high-speed pantograph-catenary The research on the train coupling system is mostly based on two systems, the typical o...
