| 摘 要： | 研究目的:为了研究高速列车受电弓头动态接触压力特性和整弓气动阻力,在中国航天空气动力技术研究院FD-09低速风洞进行试验。试验的目的是为受电弓架结构优化设计和实际使用提供科学依据。研究方法:试验方法是相对气流方向,受电弓位置分顺弓(闭口)和逆弓(开口),弓头高度分别有900 mm、1 300 mm和2 300 mm。试验风速范围从100 km/h到280 km/h,间隔为20 km/h。研究结果:试验结果表明,两种弓架气动阻力存在很大差异,因此,弓的气动力特性改进还有很大潜力。

| Abstract: | Research purposes: In order to study the dynamic touch pressure characteristics for the pantograph head and an aerodynamic drag measurement for the whole pantograph,the experimental research is conducted in FD-09 low speed wind tunnel of CAAA.The objective is provided scientific basis for the optimization design of its structure and the practical application.Research methods:Relative to the airflow direction,the pantograph state is divided a favorable pantograph(closing stomata) and an adverse pantograph(opening stomata).The heights of pantograph head are respectively 900 mm,1 300 mm,and 2 300 mm.The test wind speeds are from 100 km/h to 280 km/h at intervals of 20 km/h.Research results:The measurement results indicate that the two type of pantographs differ greatly in aerodynamic drag.Therefore,the improvement aerodynamic property on it has great potentialities. |
