铁路车辆的性能一直都是运输行业的重要课题,对于车辆的研究会影响到整个铁路交通的发展。将列车车体分成底架、侧墙、车顶等几个模块,每个模块都有自己的子模块,将车体结构模块细化到钢板、槽钢等板材结构,用有限元软件ANSYS的参数化语言APDL语言,对车体模型以命令流的形式表示,最终达到对车体结构模型参数化,方便车体结构优化,有利于对车体进行有限元仿真分析,提高车体建模分析效率,缩短车体技术更新时间,并且有助于技术交流。
The performance of railway vehicles has always been an important issue in the transportation industry. The study of vehicles will affect the development of the entire railway traffic. The train body is divided into chassis, side wall, roof and other modules, each module has its own sub-module, the body structure of the module refined to plate, channel plate structure, with the finite element software ANSYS Parametric language APDL language, the body model in the form of command flow, and ultimately achieve the parameterization of the body structure model to facilitate the optimization of body structure is conducive to the finite element analysis of the body to improve the body modeling and analysis Efficiency, shorten the body technology update time, and help to exchange technology.
