摘要
牵引变压器风机散热性能的好坏直接影响机车整车运行,是动车组牵引系统的关键部件之一。本文首先通过风机相似设计和变形设计理论对叶轮关键参数进行设计,运用ANSYS /Fluent对该其气动性能进行CFD数值模拟,然后采用Solidworks对风机结构进行优化设计,同时利用ANSYS/Workbench对其模态、结构强度等进行计算,最后结合型式试验方法验证了该风机的各项性能均合格,完全满足牵引变压器的散热需求。
The heat dissipation performance of traction transformer fan directly affects the whole locomotive operation, which is one of the key components of the Emu unit traction system. In this paper, the key parameters of the impeller are designed by the similar design and deformation design theory of the fan. The ANFD/Fluent is used for CFD numerical simulation of the aerodynamic performance. Then the structure of the fan is optimized by Solidworks, and ANSYS/Workbench is used for calculation of its mode and structural strength. Finally, the type test method is used to verify that the performance of the fan is qualified, which fully meets the heat dissipation requirements of the traction transformer.
