The brake system is very important part of the machine operating system of machine. If the machine does not stop during operation, accidents and facility damage, loss of life can cause. This ship is also in the same. In this study, After we had to change the original shape for the braking force improvement of the Mooring winch brake system, we analyzed the braking force and structural stress analysis of the changed Mooring Winch.

In the machinery, the brake system is as important part as machine's working. If the machine doesn't stopped, would be big occident. For the ships, it is important too. Use the windlass winch to stop the voyage and use mooring winch to keep the stop in the port. In this study, improve the braking power divided the brake band and search the optimize portion.

In the machinery, the brake system is as important part as machine's working. The situation of emergency stop, the machine doesn't stopped would be occur big accident. This is common things for all of machinery, also for the ships. There are two kind of mooring devices are existed on the ship. One of them, the windlass winch, is used to anchor. The other, the mooring winch is used to moor the ship in pier use the rope tied to bitt on dock. In case of previously been used mooring winch made of a steel plate, and the bolt which was connect brake band and lining broken. In this study, prevent an accident find the position of stress concentration by finite element analysis program. And removed stress concentration. And search the optimum position of the separation angle to be more efficient.

The brake system is very important part of the machine working. If the machine can't be stopped, it would be serious accident. It is the same as the ship. The mooring winch brake hold the ship in harbor. But sometimes it appeared the excessive stress and brake lining would be broken. So it is necessary to change the shape of brake system with improve the braking power. This study carried out research on optimum design like as moved the position of link pin or modified the thickness of brake band and lining.
