摘　　要：针对以进口节流调节方式进行风机噪声测试易引起测试数据失真这一问题,采用流体动力学方法利用有限元分析软件ANSYS对风机进口节流调节管段流场特性进行了数值模拟,分析结构参数对风机噪声测试的影响,为进口管道结构参数的确定和改进提供了依据。Directed at the problem that the testing data of fan noise becomes distortion viable during throttle governing, the flowing state property's numerical simulation is done in throttle governing pipe field about computational fluid dynamical by finite elements software ANSYS, and analyses the structure parameters' influence to fan noise tesing. This paper provides the foundation of entrance pipe structure parameters' determination and improvement.
