高速列车多学科仿真集成可视化平台研究

摘要

Based on the multi-discipline simulation analysis of high-speed trains CAD models,such as structure analysis,fluid analysis and noise analysis,the data interface between finite element analysis software and the visualization software was developed,the mesh simplification algorithm of CAD models and finite element models for high-speed train were studied and the mesh mergence technology of different finite element mesh was explored.The result of multi-discipline simulation for high-speed trains could be integrated on the same visualization platform.%本文在对高速列车三维CAD模型进行结构、流场、噪声等多学科仿真分析的基础上,通过有限元分析软件与可视化软件间的数据接口开发,研究高速列车CAD模型与有限元模型的网格简化方法及异构有限元模型之间的网格融合技术,实现高速列车多学科仿真分析结果在同一可视化平台上的集成.
