부분시스템 합성방법을 이용한 심해저 통합 채광시스템의 동역학 해석 연구

Abstract

The deep-seabed integrated mining system for manganese nodule consists of vertical steel pipe, intermediate buffer station, flexible pipe and self-propelled miner. For the purpose of the analysis of the Deep-seabed integrated mining system easily, a recursive subsystem jacobian method with the Finite difference method using lumped mass is developed. In order to validate the proposed method, the deep-seabed integrated mining system at water depth 500 meter has been modeled and simulation results from the proposed method are compared with the commercial software. Arithmetic operational count which is a theoretical way to evaluate computational efficiency and CPU time with Matlab code indicates that the proposed method is more efficient than the existing full jacobian method.easily, a recursive subsystem jacobian method with the Finite difference method using lumped mass is developed.
