Hence , they that flow field calculation and dynamical computation of fluid - solid coupling dynamic characteristics are carried out to search flow law in the hydraulic turbine , optimize the design of scroll casing , guide vane , blade and draft tube , and they can apply useful to the monitoring and fault diagnosis system of hydroelectric set as well 因此,为探求水轮机内部的流动规律,优化水轮机设计,为水轮机的安全稳定性运行和机组的故障诊断提供帮助。对导叶内部的流动进行流场计算和流固耦合振动特性的动力计算就显得十分必要。
The inside fashion of the sway oil pump stator is complex , its wall thickness is pockety and the metal flow law is difficult to master . at the present time , the investigation of warm extrusion forming technique for the nonuniform wall thickness forging has few to been done . the forming technique and die configuration which use for production have not achieve optimization 由于转向油泵定子的内部形状复杂,零件壁厚分布不均,金属流动规律难于掌握,目前人们对这种非均匀壁厚锻件的温挤压成形工艺研究几乎没有,其成形工艺及生产用模具结构并未达到最优化。
These landslides go with fluidization peculiarity different degree in course of their motion , and their speed and distance increase several times because of the fiuidization , thereby the disaster area greatly broaden . on the base of above , the paper studies systematically the fluidization of large high - speed rockslides in all its aspects : analyzed the aerodynamic effect in the short - range on the base of the wind turmel experiment , studied the effect of falling into pieces when landslides collides mountain ; studied the accelerating effect through high - speed collide experiment of landslides model ; and the paper reappear the overall process including set - out , collide in the short range , debris flow in the long - range of touzhai large landslide via distinct element method ( dem ) , studied the flow law and equation of different type of debris flow resulted from large landslide . as a sample to apply , the paper analyzed fluidization mechanism of touzhai landslide 基于这一点,本文对大型高速岩质滑坡的流体化现象进行了全面而系统的研究:通过风洞模型实验,研究了大型高速滑坡凌空飞行阶段的空气动力学效应,研究了飞行中滑坡岩体在与途中不动山体发尘碰撞时的解体破碎效应,通过滑坡岩体高速碰撞模型实验研究了滑坡岩体解体破碎后部分岩体的加速运动效应,并应用离散单元法再现了云南头寨沟大型滑坡启动高速、近程碰撞、远程碎屑流运动的全过程,研究了岩体解体破碎后形成不同类型碎屑流的运动规律及运动方程,并对头寨滑坡流体化运动机理进行了实例分析,取得了以下主要结论和成果: ( 1 )对于大型高速滑坡,大多在启程活动阶段已获得了高速,这使得这类滑坡在其离开剪出口之后以凌空飞行的形式向前运动,在其飞行过程中,滑坡岩体与空气强烈作用,并产生空气动力学效应,滑坡岩体在因碰撞而产生的解体破碎效应及部分岩体的加速运动效应的作用下,在远程活动阶段,以高速碎屑流的形式向前运动。
This article is mainly about the study on the dynamic characteristics of labyrinth seals and concludes the dynamic characteristic of labyrinth seals with the two - control - volume model by the means of turbulent flow theory and calculating fluid mechanics in order to further study on the flowing law of the labyrinth seals 本论文围绕迷宫密封流场动力特性系数的研究展开的,采用两控制容积模型,利用湍流理论和计算流体力学的方法,深入研究迷宫密封内部流动的规律、密封性能,获得迷宫密封的动力特性系数。
This section , based on the prediction method in the third section , researches on the passenger flow law of each station , and predicts possible passenger flow of each regular runs , which number amounts to the sum of passengers of each station who come to station in a interval on the given line , and finds out the congregation of optimized dispatch plans by using genetic algorithm , then , selects the best dispatch plan from the above congregation by using fahp method to evaluate 这部分是在第三部分公共交通线路每日客流量预测的基础上,研究了车站客流规律以及在预测条件下首站发出的各车次依次经过线路各个车站时可能产生的客运量,并研究了用遗传算法计算了调度优化方案组合,然后用模糊层次方法综合评出优化方案。
