AI Technical Summary

Benefits of technology

This patented technology allows for simulations that involve simulating complex structures such as railways or transportation networks without requiring them be installed separately from each others' infrastructure. It uses virtual reality (VR) software tools like VMware® Xbox 360), which can communicate over computer network interfaces while interacting with external sources. These simulations allow users to study how these structures work together more effectively than they would have if it were built into their own equipment.

Problems solved by technology

This patented technical problem addressed in this patents relates to the difficulty involved when building up a sufficient amount of data needed to accurately predict how well certain parts or components (such as wheels) will behave after long hours at very fast speeds while also ensuring accurate testing without sacrificially increasing costs due to increased maintenance work required overall. Current static simulations have limitations such as lacked flexibility, requiring separate physical models based upon each test's needs, limited functionality, and difficult implementation across multiple scenarios.

Abstract

A train dynamics real-time simulation platform comprises a plurality of simulation models, each simulation model comprises a simulation dynamics calculation unit and an interface unit, and the interface unit is used for communicating with a train control system, a monitoring system, a screen display and the like of a train to be tested. The dynamics calculation unit is used for calculating the acting force borne by each vehicle and dynamics performance indexes. The simulation model comprises a one-dimensional longitudinal dynamic model; a one-dimensional semi-physical longitudinal dynamic model; a multi-train longitudinal dynamics model; a longitudinal kinetic model based on adhesion; a three-dimensional semi-physical dynamic model; each dynamic real-time simulation model in the simulation platform makes simulation conforming to a line and a train structure as much as possible, the requirements of various simulation tests of the train for a dynamic simulation environment are met, and the universal effect is achieved.
