DESIGN AND ANALYSIS OF GEOMETRICAL PARAMETERS INFLUENCING ON CURVIC COUPLING

the as widely observed that bolts turn loose,when subjected to fluctuating loads. Thi s ultimately reduces the force of bolt and leads to fail in the performance. Such failures can cause sudden great damage in safety critical applications. Therefore,it is necessary to design couplings wit h high positioning a ccuracy and high indexing st iffness . So the concept of curvic coupling was come in to existence. The stresses induced in the coupling ha ve been analyzed by analytical method . A three dimensional finite element model of curvi c coupling is developed in finite element software to compare to analytical results . The model consists of coupling assembly. A moment is applied on co upling & simulates the effects. Based on these results,a finite element analysis should be used if a greater level of detail is required for the analysis of curvic coupling. https://www.ijiert.org/paper-details?paper_id=14127
