Finite Element Analysis of Grinding Stress for Fiber Optic Connector(Ceramic Ferrule)

유한요소법을 이용한 광통신용 페룰($ZrO_2$)의 연삭거동에 관한 해석적 연구

Ceramic ferrules which are major parts of the fiber optic connectors are requiring high precisions in grinding. After grinding, it is the problem that subsurface damages cannot be removed. The objective of this study was to analyze the grinding force and the associated stress generated in a ceramic ferrule during cylindrically external griding using finite element analysis(FEA). A two-dimensional finite element model was constructed with the grinding parameters and the mechanical properties of the ferrule as input variables. The size of the geometric model was the same with ceramic ferrule. The experimental results are investigated by SEM photograph and compared with the results from FEM. The result of FEA showed a good agreement with that of experiment.
