摘要
通过建立铁路隔振沟对轨道减振分析的力学模型,运用ANSYS大型有限元通用软件对隔振沟深度、隔振沟宽度及隔振沟位置对隔振沟减振效果进行分析。结果表明:隔振沟深度是影响减振效果的主要因素,随着隔振沟深度的增大其减振效果逐渐增强;而隔振沟宽度和隔振沟位置对隔振沟减振效果影响不大;隔振沟对高频振动的减振效果尤为明显。
Establishing a mechanical model for analyzing railway vibration reduction by trenches this paper uses the universal finite - element software ANSYS to analyze the reduction effect of different characteristics which influence resuiting vibration reduction, such as the depth, the width or the location of trenches. It is shown that the depth is the dominating factor and the width or the location of trenches has very little effect on vibration reduction. With the depth increasing, the effect of vibration reduction is improved and furthermore the vibration reduction by trenches is more fit for the high frequency vibration.
