심해저 연약지반 무한궤도 차량 동력학에 미치는 유체력 영향

Abstract

This paper concerns about dynamic analysis of an underwater test miner, which operates on cohesive soil. The test miner is modeled by means of a commercial software. A terramechanics model of cohesive soft soil is implemented to the software and applied to dynamic analysis of the test miner model. The hydrodynamic force and moment are included in the test miner's dynamics. The hydrodynamic effects on the performance of tracked vehicle are investigated by numerical simulations.
