In this work , the space is discretizied using tetrahedral meshing grid , and the flow is described by indoor zero equation model , and simple algorithm is applied 本文采用四面体网格对空间离散,紊流模型采用室内零方程模型,选用smple算法。
To solve the problem the technology used by the elements of the program are : vertical flat steel welding between the horizontal poles of a number of encryption steel , the steel mesh grid formation plate 解决该问题所采用的技术方案要点是:纵向的扁钢之间的横向杆上焊接若干加密钢条,形成网状的钢格板。
There is a linear relation of the logarithm between the pressure difference in round seepage flow region and the radius , for the same accuracy , it is better to select a center mesh grid that is a isometry system with inr interval 模型离散化时必须满足流量、体积守恒。圆形渗流区域内的压力差随半径是对数的线性关系,为保证相同计算精度,选择对lnr来说等距的中心网格系统。
It was indicated that the calculated results of positive problem have relatively small error and are acceptable , the change of the size of electrodes influences the calculated results slightly , and the increase of mesh grid is helpful to improve the precision of calculation 分析结果表明:正问题的计算结果误差较小,令人满意;电极尺寸的改变对计算结果影响不大;网格剖分数增大有利于提高计算精度。
According to experimental data and related standard , the finite element model of frame has been set based on its geometric model through simplified processing , selecting element , dividing mesh grids , load cases setting and putting characteristic etc . on the basis of this , the integrated finite element model of motorcycle has been established including frame , engine , suspension , wheel , rider and oil box etc . to understand the relationship and dynamic property of frame and integrated motorcycle , mode analysis and frequency response analysis have been done 根据实验测试数据和有关标准规范,以总体设计阶段得出的车架几何模型为基础,通过模型简化、单元类型确定、网格划分、工况设置、边界处理、物理特性赋予等,建立车架的有限元模型。并基于此,建立整车的有限元模型,包括车架、发动机、悬架、轮胎、乘员、油箱等。
