Finally it analyzes the feasibility that using hydromechanics to analyze traffic flow by contrasting various characters between traffic flow and fluid flow. It analyzes influence of road alignment to basic expressway segment capacity by hydromechanics, and obtains viscous resistance and viscous movement differential equation when the vehicle drives on circular curve segment of expressway. And it infers that viscous resistance is correlated with sideway force coefficient, slope of crown and radius of circular curve. Radius of circular curve, sideway force coefficient and slope of crown are bigger, viscous resistance is smaller, the influence to capacity is smaller when the vehicle is running on nearside lane of circular curve; but radius of circular curve and sideway force coefficient are bigger, slope of crown is smaller, viscous resistance is smaller, the influence to capacity is smaller when the vehicle is running on fast lane of circular curve.
最后通过对比交通流与流体流的相似性,运用流体力学分析了道路线形对快速路基本路段通行能力的影响,求出了车辆在曲线路段的粘性阻力,建立了车辆在曲线路段的粘性运动微分方程,并由此推知,粘性阻力与横向力系数、路拱横坡度和圆曲线半径都有关系,当车辆在圆曲线外侧车道上行驶时,圆曲线半径、横向力系数和路拱横坡度越大,粘性阻力就越小,对道路的通行能力影响就越小;而当车辆在圆曲线内侧车道上行驶时,圆曲线半径和横向力系数越大,路拱横坡度越小,粘性阻力就越小,对道路的通行能力影响就越小。

In the computation of aerodynamic forces, the present work is based on the work of Morino et al., but the following aspects are improved:(1) In computing the steady transonic aerodynamic load, the steady transonic nonlinear integral equation is solved by relaxation-iteration method in this thesis, instead of solving the time dependent transonic nonlinear integral equation, so that the computing time is saved greatly;(2) The influence coeifficients represented by volume integral are transformed to surface integral by using the Gaussian Theorem, so the analytical form of these coeifficients can be obtained and this leads to be more convenient to analyse and compile computer program;(3) The shock capturing method is used in every time step in present work, no shock moving term is added in the integral equation, so that it is more convenient and simpler to treat.
在气动力计算方面,本文基于Morino等人的工作,作了如下几方面的改进:(1)在计算定常跨音速流场(作为非定常绕流计算的初场)时,本文采用松驰迭代法直接求解跨音速定常非线性积分方程,而不是采用时间相关法求解非定常非线性积分方程,这样大大节省了计算机时;(2)将以体积分形式出现的影响系数化为面积分,并获得解析公式,这样便于分析和编写程序;(3)对运动的激波,本文通过在每一个时间步长上采用激波捕捉法而得到,而不是在积分方程中附加激波运动项,因而处理起来简单方便得多。
