The train with the high train body strength and the low running resistance comprises stand columns located on the two sides of a train body, a jet flow channel is formed in the train body, stand column cavities are formed in the stand columns, and a first straight line area, a bending area and a second straight line area are sequentially arranged in each stand column cavity from left to right; a first jet flow channel is arranged at one end of the jet flow channel, a first jet flow outlet is formed in one end of the first jet flow channel, a second jet flow outlet is formed in one end of the second jet flow channel, the first jet flow outlet is located above the second jet flow outlet, an opening of the first jet flow outlet inclines downwards, and an opening of the second jet flow outlet inclines upwards. Air resistance during high-speed running of a train is greatly reduced, section defects are not prone to being generated when the rail transit door stand column is bent, the yield is high, and the method is suitable for large-scale production of aluminum alloy door stand column products.
本发明公开了一种高车身强度低运行阻力的列车,包括位于车体两侧的立柱,该车体内部设置有射流通道,立柱的内部开设有立柱腔,且立柱腔的内部从左至右依次设置有第一直线区、压弯区及第二直线区;射流通道的一端设置有第一射流通道,第一射流通道的一端设置有第一射流出口,第二射流通道的一端设置有第二射流出口,且第一射流出口位于第二射流出口的上方,第一射流出口的开口倾斜向下,第二射流出口的开口倾斜向上。本发明大幅降低了列车高速运行时的空气阻力,并使轨道交通门立柱压弯时不易产生截面缺陷,成品率高,适合铝合金门立柱产品的规模化生产。
