심해저 채광시스템의 부분시스템 활용 통합 해석 기법 연구

Abstract

Three subsystem synthesis methods with stiff spring, constraint, and constraint elimination have been proposed for an efficient analysis of the beam model in a deep sea-bed mining system. A deep sea-bed mining system consists of a lifting pipe, a buffer, a mining vessel, a carrier, a flexible pipe, and a miner vehicle. Efficiency analysis of the sea-bed mining system is necessary in order that set up the controlled miner vehicle on the sea-floor. For the efficient analysis, subsystem synthesis methods for the lifting pipe and a flexible pipe can be utilized. Efficiency and accuracy of the methods has been investigated using beam model of the sea-bed mining system. Among three proposed methods, the constraint elimination method has turned out to be the most effective one.ipe, a buffer, a mining vessel, a carrier, a flexible pipe, and a miner vehicle.
