机车车辆排风风帽阻力特性的试验研究

Experimental investigation on drag characteristic of the exhaust cap of locomotive and rolling stock

采用试验方法,对机车车辆排风风帽的阻力特性进行了研究,得出了排风风帽阻力与排风量之间的关系。通过计算得出排风风帽的阻力系数,可用于机车车辆排风风帽的设计。

Drag characteristics of the exhaust cap of locomotive and rolling stock was studied by experiment,and the relationship between the exhaust cap pressure loss and air flow rate was obtained.Based on the experimental data,the drag coefficient of the exhaust cap,which can be used for the design of the exhaust cap of locomotive and rolling stock,was determined by calculation.
