The quadratic regression orthogonal rotary method was adopted to study the offect of three different mixing homogeneity : mixing time, block coefficient and rotary speed of the paddle shaft, also study the dominant effect, the single effect and interactive effect.

通过二次回归正交旋转组合试验，对影响翻转式双轴桨叶混合机混合均匀度的3个因素(混合时间、充满系数及桨叶轴转速)以及对混合的主效应、单因素效应、两因素间的交互效应进行了分析，并且得出了各因素水平间的最佳组合工艺。

And the "three-factor quadratic regression orthogonal rotary method" was adopted to study mixing performance of the mixer,after the machine had been designed and trial-produced. It was showed that the optimum technological parameters for mixing time, block coefficient and rotary speed of the paddle shaft were 180 s, 0.75 and 56 r/min, respectively. At the same time, the remains in the bin was little (0.015%). The effe...

为了提高双轴桨叶混合机的混合性能，采用二次回归正交旋转组合试验，对设计样机进行混合均匀度及机内残留率的试验研究，得出了其工作参数的合理组合：混合时间为180s，充满系数为0.75，桨叶轴转速为56r/min；机内残留量极小(约为0.015%)，满足其作为配合饲料生产，尤其是预混合饲料生产的工艺要求，也为进一步改进设计提供了依据。

At the same time, two different coal feeding methods - coal from the vertical pipe and from the inserted tube, were separately simulated and analyzed. According to the internal flow distributions under two different coal feeding methods, we made a judgement that the former feeding method was better than the latter.

为了进一步对煤粉捏合器进行优化设计，按照上述方法本文从改变旋转轴的转速、改变煤粉跟溶剂油的进口流量、改变搅拌桨叶形式以及改变搅拌桨叶外端与混合槽壁间距几个方面重新进行了数值模拟与分析。

The results show that the flap hinge spring rate has a great effect on helicopter stability and control, but precone and prelag angle,lag hinge spring rate and blade lag motion can be negligible...

分析结果表明：旋翼的预锥角和预掠角对直升机全机的稳定性和操纵性的影响可以略去不计，而桨叶根部挥舞方向上的弹性约束刚度对直升机全机的操纵稳定性有较大影响，摆振方向上的弹性约束刚度和桨叶的摆振运动对直升机稳定性的影响不大，可以略去不计。
