  • sleeper : n 1 睡眠者;懶人;死人。2 有(臥)鋪(設備的)飛機;【鐵路】〈美國〉臥車,臥鋪;〈英國〉枕木;(...
  • beam : n 1 梁,棟梁,桁條;(船的)橫梁。2 船幅;(動物、人的)體幅。3 (秤)桿,杠桿,(織機的)卷軸,...
  1. We consider each sleeper as an abutment of opposite forces, rails on horizontal sleepers as a mock dispersed elastic ground beam model and trains as moving load on beams. geometric roughness and damping are not taken into consideration

    將每根枕木考慮成一個支座反力,將橫向枕木支承的鋼軌模擬成離散的彈性地基梁模型,將列車考慮成一個作用在樑上的移動荷載。
  2. The major research of this paper is that : 1, it is analyze the displacement response of the elastic - foundation beam by the static loads and the moving loads, the dynamic response of winkler beam, analyze the influence of the sleeper in the dynamic response of the rail system. and compare the result with the experiment formulation. it is concluded that the continuous model only fit for the lower moving velocity of loads

    本文主要進行了以下幾方面的研究: 1 、首先對靜力荷載作用下彈性地基梁的位移反應、文克爾梁模型的動力響應,及枕木在軌道系統動力響應中的作用進行了分析,並與傳統採用的經驗公式進行對比,以此分析了連續性模型只適用於荷載移動速度較低的情況下,在速度較高的情況下,特別是接近臨界速度時,連續性模型是無效的。
