- 摘要:
- 利用最小二乘法原理对 T40-2A 轴流风机的气动性能实测试验数据进行了二次曲线拟合, 得出了风压-风量和功率-风量之间的回归曲线方程, 并运用回归分析原理对拟合曲线的回归效果进行了显著性检验, 建立了该风机的无因次性能回归曲线模型, 为实现该系列轴流风机在轴流式风力灭火机中的应用打下了良好的理论基础。
- Abstract:
- The aerodynamic performance test data of T40-2A axial fan performance has been quadratically fitted into curve onthe principle of least square method.The wind pressure-air volume and power-air volume regression curve equations weregiven.The regression results of the fitting curve were conducted the significance test on the principle of regression analysis.The non-dimensional performance regression curve model of T40-2A axial fan was set up.It is valuable to lay a good theo-retical basis on the realization of the series axial fan applied in the axial -flow pneumatic extinguisher.
