对矿用局扇的三种目标函数：局扇级全压效率、局扇级噪声声功率和两者有机构成的联合目标函数进行了优化，通过对比分析其结果，提出了一种把局扇级全压效率与级噪声声功丰有机地结合起来，构成联合目标函数进行优化，以获得高效低噪局扇主要参数的设计方法
Three objective functions of mine fan are optimized: the total pressure efficiency of bureau sector, sound power of bureau sector noise and the joint objective function of organic composition of the two are optimized. By comparing the results, Level total pressure efficiency and level noise sound Gong organically combined to form a joint objective function optimization, in order to obtain a high efficiency low noise fan the main parameters of the design method
