利用通用有限元软件ANSYS的APDL参数化建模技术,建立桥上弹性支承块无砟轨道模型。利用ANSYS的模态分析功能,分别计算块下刚度不变而轨下刚度变化和轨下刚度不变而块下刚度变化两种情况下模型频率,并分析频率的变化规律,得出一定的结论。
利用通用有限元軟件ANSYS的APDL參數化建模技術,建立橋上彈性支承塊無砟軌道模型。利用ANSYS的模態分析功能,分彆計算塊下剛度不變而軌下剛度變化和軌下剛度不變而塊下剛度變化兩種情況下模型頻率,併分析頻率的變化規律,得齣一定的結論。

The low vibration track on bridge model is established through the APDL parametric modeling technology of ANSYS finite element software.Utilizing the model analysis function,calculated the model frequency respectively both when the stiffness under the concrete block unchanged but the stiffness under the rail changed and when the stiffness under the concrete block changed but the stiffness under the rail unchanged.Analysising and comparing the variations of frequency and draw some conclusions.
