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。
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.
