低压轴流通风机降噪的优化设计

Optimization for Reducig Noise of Low Pressure Axial Fan

介绍了与传统设计方法不同的优化设计。以风机噪声为目标 ,取叶轮直径、轮毂比及转速为设计变量 ,通过优化设计程序 ,可以使所设计的风机噪声尽可能小。实际算例表明 ,优化设计比传统设计有很大的优越性。

Optimization design which is different from traditional design method is introduced.Taking fan noise as a target,impeller diameter,hub ratio & speed as design variables ,the fan noise can be reduced as low as possible by optimization design program.Actual calculation shows that optimization has great advantages than traditional design method.
