摘要
本文运用最小二乘法和通风机的相似定律,用实测数据拟合了矿井通风机无因次性能曲线方程;根据矿井风道网路的通风特性,构建矿井通风网络的特性曲线方程,然后用弦截法计算矿井通风机运行工况点,从而建立通风机计算机选型设计数学模型。通过计算机辅助实例分析,验证了所建立数学模型的适用性。
On the basis of least square and law of similarity of ventilator, the dimensionless performance curve equations of mine ventilator by operating data are fitted and the characteristic curve equation of mine ventilating network according to its characteristic factors is constructed. The mathematic model for mine computer aided lectotype design is built after calculation of operating points by chord-truncating method. The applicability of this model is verified by example.
