Moreover,it also discussed the problem about influence of wind velocity to fire scale and the safe velocity for running to next station when the train was in fire,whi.
本研究运用计算流体力学(CFD)的方法,对运行中地铁列车周围不同部位的相对风速及其速度场分布特性进行了模拟分析;重点讨论了当地铁列车区间隧道着火时,考虑到风助火势的影响,行进中地铁列车的行驶速度对火势蔓延的影响;进而对地铁列车区间隧道着火时的安全行驶速度进行了初步的探讨。
The influence on rut of upgrade section with continuous slope of horizontal force,vehicle speed,axle load and temperature is analyzed.
在调查我国某高速公路某段连续上坡沥青路面车辙病害的基础上,利用粘弹性理论,采用Burges模型模拟沥青混合料粘弹特性,计算了汽车通行一次情况下沥青路面的残余剪应变,全面分析水平力、车辆行驶速度、轴载和温度对上坡沥青路面车辙的影响。
