심해 환경인자를 고려한 망간단괴 시험집광기 주행장치의 다구치 강건설계

Abstract

A deep-sea ocean mining collector can consist of 4 parts: pickup device; crusher; transporting equipment to pump the crushed nodules through a flexible hose to the mother station and tracked vehicle traveling on a semi-liquid layer of deep-sea soil. The tracked vehicle is an essential component in the self-propelled mining system moving on soft soil. Performance of the tracked vehicle is influenced by environmental factor; track velocity, tilt angle, shear stress of deep-sea bed, velocity ratio, oceanic current and reaction forces of flexible hose. In this papaer, we introduce Taguchi method to acquire robust design of deep-see ocean mining system for environmental factor.
