Abstract: To address the challenges of insufficient automation in scene construction, inconvenient multi-role multi-user collaboration, poor analysis timeliness of analysis, and high client hardware requirements in the traditional train dynamics analysis processes, a cloud simulation-driven train dynamics collaborative visualization analysis framework driven by simulation was proposed. A train dynamics simulation and visualization analysis framework, a remote visualization interaction framework, and a solver integration model for real-time analysis were designed. These respectively achieved service-oriented multi-dimensional visualization analysis scene construction, multi-role and multi-group collaborative remote visualization analysis, and efficient module interconnection and node elastic expansion. Based on the proposed framework, a software system was built and validated in the project. The validation results show that the framework and system have outstanding visualization performance and concurrent solving capabilities while ensuring accuracy. The successful applications of the framework also indicate that cloud simulation has great potential for use in train dynamics visualization analysis.
