摘要
通过对缩比为1:8高速列车模型在8m×6m风洞进行的列车风洞试验,研究列车零部件其中包括空调导流罩,受电弓,受电弓导流罩,车门的形状位置发生变化时,对列车气动性能的影响,并对试验结果进行了分析,研究结果表明:受电弓的位置和布置形式会对整车阻力产生影响,当中间车门凹陷时,整车阻力增加,加有导流结构的门有效的改善了门凹陷引起的阻力增加,空调导流罩很好的顺形结构对阻力影响不大。
Based on the shrinkage ratio of 1：8 High--speed train model in 8 m ＊ 6 m the train wind tunnel lest of wind tunnel to study the train parts including air conditioning dome, pantograph and pantograph dome. the shape of the door location changes, their influences on train aerodynamic performance, and the test resuhs are analyzed, and the resuhs show that the location of the pantograph and its layout could affect the vehicle resistance. When the middle door sag, the vehicle resistance increased, with the door of the diversion structure is effectively improved the sag resistance increased problems. But air conditioning dome with good conformal structure has little impact to its resistance.
