摘　　要：针对微型电动汽车增程器运行噪声过大的问题,设计了一款隔声罩并建立增程器隔声罩CFD模型,同时采用Realizable k-ε湍流模型,对隔声罩内的流场和温度场进行仿真分析,考察隔声罩结构的合理性以及优缺点,可为优化隔声罩结构设计提供技术支持。Aiming at the noise of Micro-Electric Vehicle Range Extender, the author design a structure of enclosure and build a CFD simulation model, which adopts the Realizable k-E turbulence model to simulate the flow field and the temperature field. This model could inspect the advantages and disadvantages of the enclosure structure, which can supply technical support for the design of enclosure structure.
