연약지반 무한궤도차량의 다물체 동적거동 해석

Abstract

This paper concerns about dynamic analysis of an underwater test miner, which operates on cohesive soil. The test miner consists of tracked vehicle and pick-up device. The motion of pick-up device relative to the vehicle chassis is controlled by two pairs of hydraulic cylinders. 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 dynamic responses of test miner are studied with respect to of four different types of terrain conditions.
