A study on the shape design and analysis of rail fastener

레일 체결구의 형상설계 및 해석 기술에 관한 연구

In this paper, a technique for the shape design and analysis of rail fastener is presented. KRRI's own 3 type fasteners are developed after due consideration for tile aspects of installation, maintenance, and cost of fastener. Numerical by using commercial FEM program COSMOS/Works are carried out to determine the optimal shape of fastener clip. Front tile manufactured models and numerical results, the developed fasteners show tile possibility to be commercialized. But in order to have their competitiveness on the markets, further studies are required for the demonstration of performance through laboratory and field tests
