  1. Some conclusions are drawn : 1 ) effect of inertial force from superstructures on the lateral seismic response of single pile can not be ignored ; 2 ) the lateral seismic response of single pile induced by far - field earthquake are mainly affected by acceleration mass of superstructure > site eigenperiod. it increases with the increment of accele ration and mass of superstructure. as the site characteristic frequency approaches the self - oscillation frequency of the pile, sympathetic vibration occurs and the value of lateral seismic response reaches maximum ; 3 ) as the stiffness ratio of pile to soil increase, the relative displacement of pile to soil increases ; 4 ) the lateral seismic response of fixed - head pile is much smaller than that of free - head pile

    將其解析解與具體的的抗震設防烈度和場地特徵周期結合起來，計算分析了成層地基中單樁的橫向地震響應，得到了以下結論： 1 ）上部結構慣性力對樁的橫向地震響應的影響不可忽略； 2 ）成層地基中的單樁的橫向地震響應主要受地震基本加速度、場地特徵周期、上部結構質量的影響，隨地震基本加速度、上部結構質量的增大而增大；場地特徵頻率越接近樁基自振頻率，樁基地震響應越大，等於自振頻率時，由於發生共振現象，樁基響應幅值最大； 3 ）樁土剛度比越大，樁土之間的相對位移的幅值越大； 4 ）樁頂固接的連接方式，可以有效地降低地震時單樁的橫向地震響應。

  5. In the processing of the numerical simulation of lrv dynamics, knowing from the creepages of irw first, wheel profile has sensitive effect on irw creepages, so the wheel profile should be selected cautiously to optimal the vehicle dynamic behaviors. next, the longitudinally creep force is disappeared, so the self - oscillation vvill do n ' t occur and the bogie is stability. while the natural steering action of vheelset is lost which means that some sort of steering action is necessary to keep the wheelset appropriately aligned on a curve

    在輕軌車輛動力學數字模擬計算中，通過對獨立旋轉車輪蠕滑率的分析知，車輪踏面外形對其影響十分敏感，適當的選取獨立旋轉車輪踏面的外形可以優化車輛的動力學性能；採用獨立旋轉車輪，縱向蠕滑力不復存在，自激振動不會發生，轉向架也就穩定；但同時，常規輪對具有的自動導向功能西南交通大學碩士研究生學位論文第11頁也失去了。
  6.
