【摘要】 针对高原环境下机车牵引通风系统的通风散热问题，对比平原环境下的计算结果，对高原工况不同海拔条件下各参数进行高原修正，经CFD仿真计算验证冷却系统在高原环境下能否正常工作并保证冷却效果。针对风机性能曲线、管网阻力曲线、牵引电机及动力间阻力曲线进行高原修正，并选取不同海拔下的高原大气条件进行仿真计算。更多还原

【Abstract】 Aiming at the ventilation and heat dissipation issues of locomotive traction ventilation systems in plateau environment, we corrected various parameters under different altitude conditions in plateau environment comparing with the calculation results in plain environments, and performed the CFD simulation calculations to verify whether the cooling system can work normally and ensure cooling effectiveness in plateau environment. We corrected the fan performance curve,pipeline resistance curve, traction motor and power room resistance curve for highland conditions, and performed the simulation calculations by selecting plateau atmospheric conditions at different altitudes.更多还原
