高速列车气动减阻及转向架区域防冰雪数据集

数据集主要内容是通过大型工作站进行数值仿真计算，仿真软件以商用软件Fluent为主，数据处理为EnSight等软件，计算参数等均通过查阅文献和实际需求进行自主设定。高速列车气动减阻，包括不同工况下个各节车辆气动阻力系数及各关键部位气动阻力系数。转向架区域防冰雪包含高速列车转向架不同区域、防积雪导流槽结构以及三种高寒动车组转向架侧面裙板包裹形式等的数值仿真结果数据。于2020年10月至2022年12月采集，采集地点为中南大学轨道交通安全教育部重点实验室，设备为课题组工作站电脑。数据量45MB。This dataset comprises numerical simulation results generated using high-performance workstations. The commercial computational fluid dynamics software Fluent was employed as the primary simulation tool, with post-processing carried out via software such as EnSight. All simulation parameters were independently configured based on literature reviews and practical engineering requirements. The dataset covers two main research topics related to high-speed train aerodynamics: 1) Aerodynamic drag reduction: including aerodynamic drag coefficients of each train carriage and key components under various operating conditions; 2) Bogie area anti-icing and snow accumulation: numerical simulation results of different regions of high-speed train bogies, snow-guiding groove structures, and three types of side skirt wrapping configurations for cold-resistant electric multiple unit (EMU) bogies. The dataset was collected from October 2020 to December 2022 at the Key Laboratory of Track Traffic Safety (Ministry of Education), Central South University, using workstations owned by the research group. The total size of the dataset is 45 MB.
