Abstract

A deep-sea ocean mining collector consists 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 noise factors which include environmental factors and operational factors: track velocity; tilt angle; velocity ratio; oceanic current; shear strength of deep-sea bed; reaction forces of flexible hose. Taguchi method is an engineering methodology to improve the quality of a product by minimizing the efforts of variations without eliminating the uncontrollable causes. In this paper, we introduce Taguchi method to acquire robust design for noise factors.
