水力测功器

This article, using finite element method, calculated the assembly stress, working stress and modality parameter of hydraulic dynamometry rotor, and then simulatively researched the assembly and bearing process of the rotor.

本文用有限元方法计算了水力测功器转子的装配应力、工作应力及模态参数，进而，对转子的装配及承载过程进行了仿真研究。

Hydraulic dynamometry rotor was casted from brass alloy. Because of the working requirement for driving liquid, the laminas of the rotor are assembled slantways and have a complicated structure .

水力测功器转子是由黄铜合金铸造而成，由于转子工作时驱动液体的需要，叶片均呈倾斜状，结构比较复杂。

Not only is it very important to produce and use the device, but it also provided theory basis for optimizing production, lucubrating and creating high quality production.

对水力测功器的生产和使用具有重要的现实意义，为产品优化、进一步深入研究以及创优质产品提供了基础。

The above analysis and calculation results resolved the problem that how to reasonably select the shrink rang during the design process and confirmed the assembly temperature under different shrink fit, which avoided the blindness of assembly, provided some better suggestion for the design of the rotor and offered reference datum for the safety and the steady running of the rotor.

上述分析计算结果解决了转子设计时过盈的合理选取的问题，并确定了在不同过盈配合情况下转子安装时所需的加热温度值，避免了安装过程的盲目性，对转子的设计工作提供了一些较好的解决方案，为水力测功器安全、稳定运行提供了参考数据。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
