摘　　要：采用CFD仿真计算对3000马力混合动力机车多部件通风冷却系统进行研究,改进风道结构,确保各牵引电机风量满足要求且相对均匀,同时保证辅助电气间和变流电气柜的冷却通风量.搭建全尺寸地面模拟试验台,采用1∶1比例风道模型、真实产品作为各终端负载,进行多部件的通风系统地面模拟试验,结果表明设计思路、方案是正确和可行的,开创了全新的多部件通风冷却的研究方法.The CFD simulation calculation is used to study the multi-component ventilation and cooling system of the 3000-horsepower hybrid locomotive,and the air duct structure is improved to ensure that the air volume of each traction motor meets the requirements and is relatively uniform,while ensuring the cooling and ventilation of the auxiliary electrical room and the variable current electrical cabinet.The full-scale ground simulation test rig was built,and the 1∶1 proportional air duct model and the real product were used as the terminal loads to carry out the ground simulation test of the multi-parts ventilation system.The results show that the design and solutions are correct and feasible,which presents a new research methods for the multi-component ventilation cooling system.
