中鋼鐵水運輸鐵路之全線道岔軌道至今仍使用木軌枕舖設,目前想改換成預力軌枕,以提高其成本效益。
本研究主要以有限元素分析軟體(ANSYS)來建立道岔軌道之雙層離散支承模型,初期以小模型分析為主,旨在局部參數之探討,經過各小模型的探討後,將有助於道岔軌道模型之建立。
魚雷車以每小時12公里之速度行駛於道岔區,其作用於道岔軌道之力,經由動力分析後,可獲得道岔軌枕的剪力值及彎矩值,再由此區的軌枕中,找出最大剪力值及最大彎矩值,以做為軌枕的設計參考,同時一併把扣件的最大軸力值找出。目前在中鋼鐵水運輸鐵路的道岔區有木軌枕之現場監測,將來當預力軌枕安裝時,預計再做一次現場監測,以更進一步的了解道岔軌枕之動力反應。
This study is used for a project which tries to exchange the wood sleepers into concrete sleepers in China Steel.
The package ANSYS is used for the finite element analys is to establish a model of the railway crossings. A discrete double layer model of the foundation is included. A series of parametric studies were performed first to get reasonable data for the complicated crossing system. Also, a big model for the entire crossing was established.
The speed of torpedo car is approximately at 12 km/hr. Through the static and dynamic analyses, the moments and shears in the sleepers and axial forces in the fasteners were obtained. Those data are used for the design of sleeper. Also, a monitoring system uses the digital cameras are established in the field to get the corresponding responses of crossing systems. Those data can be used to verify and modify the numerical model.
