论文首先在直角坐标系下,给出了fdtd差分方程和周期性边界条件的具体形式,并编写程序,分析了周期性加载金属片矩形波导的色散特性。 - According to different mechanisms , there exist several types of resonance , including the bridge resonance induced by the periodical actions of moving load series of the weights , centrifugal forces and lateral winds of vehicles , the bridge resonance induced by the loading rates of moving load series of vehicles , the bridge resonance induced by the periodical loading of train vehicles excited by rail irregularities , wheel flats and hunting movements , and the vehicle resonance induced by periodical actions of the regular arrangement of bridge spans and their deflections
根据发生机理的不同，车桥系统可能发生几种不同形式的共振，包括由车辆重量、离心力、横向平均风荷载等形成移动荷载列的周期性动力作用引起的桥梁共振，由移动荷载列加载速率引起的桥梁共振，由轨道不平顺、车轮扁疤、轮对蛇行等周期性加载引起的桥梁共振；由桥跨的规则性排列及其挠度的影响，对移动车辆形成周期性动力作用使车辆出现的共振。
