摘要
为降低超高速动车组的气动阻力,综合国内外高速动车组头型设计要素,设计了速度500 km/h超高速动车组头型。基于美工效果、人机工程、限界、曲线通过、气动力、气动噪声等多项指标,完成了超高速动车组头型气动性能综合评估、头型优选和试验验证。研究数据可为更高速度级动车组设计和气动性能数据库的扩展提供技术储备。
To decrease the aerodynamic drag of super high-speed EMUs, integrating high-speed EMUs head type design elements at home and abroad together, a new head type for super high-speed EMUs with speed of 500 km/h was designed. Based on indicators including graphic effects, man-machine engineering, gauge, curve-passing ability, aerodynamic force and aerodynamic noise, comprehensive evaluation, shape optimization and experimental verifi cation of aerodynamic performance for the super high-speed EMUs head type was completed. The research data could provide technical support for higher level speed EMUs design and the expansion of the aerodynamic performance database.
