Abstract

Abstract:

Since almost all the software in the railway vehicle field is controlled by foreign capital, it is difficult to catch up with the development of independent vehicle system software based on single machine deployment mode in a short time. In view of this, a set of autonomous and controllable vehicle system dynamics software architecture based on cloud platform is proposed. Based on the railway vehicle system dynamics and cloud services, a cloud platform with automatic process modeling, cloud computing,post-processing analysis is built. A simulation model of a trailer caris applied in the platform, and compared with the SIMPACK simulation results to verify the availability and reliability of the platform.The implementation of the platform could replace the commonly used software for railway vehicle dynamics to a certain extent, which can provide reference for the development of similar software.

Key words: railway vehicle system, autonomous controllable, simulation contrast, dynamic performance, cloud platform
