Abstract
Coupling bolts replace conventional fitted bolts in applications where operator's safety during assembly/disassembly is a concern or where the cost of process interruption is significant. Coupling bolt has been installed on rotating flange couplings in a wide range of marine and power applications worldwide. The coupling bolt has been approved for use by all leading international and national classification societies and regulatory bodies.

The coupling bolt is a hydraulically tensioned fitted bolt, which creates a stable and rigid link between the coupling flanges and simplifies assembling and disassembling. FE simulation was performed by the commercial code ANSYS 11.0. Structure analysis is carried out in order to confirm the condition of bolt sets. Parametric analysis is carried out in order to understand the effects of design parameters. The first parameter is initial clearance between bore and sleeve which values are 0.025, 0.035 and 0.065 mm, respectively. The second parameter is sleeve thickness which values are different for each type. The last parameter is taper angle of sleeve which values are 1.8°, 3.3° and 4.7°, respectively.

Based on the result of the simulation, it can be concluded in order to make sufficient contact pressure. The small angle of sleeve is better than the large angle of sleeve. The small initial clearance between bore and sleeve is better than the large clearance.
