무한궤도 차량의 부식 현상 모델링 방법 및 궤도 부식으로 인한 차체와의 간섭에 대한 연구

Abstract

This paper proposes numerical modeling method of corrosion phenomenon and this method is applied to study on the interference with tracked system and vehicle platform. The subject of study is MineRo which was designed to four rows tracked vehicle. In 2013, the real seas experiment of MineRo was conducted and was discovered a damage of vehicle platform after the experiment. A reason of the damage is expected to corrosion of the tracked system. This hypothesis is verified through multi-body dynamic simulation in this study. The dynamic analysis model of MineRo has been built in the commercial software of DAFUL. Also, three parameters(k, c, μ) are studied to make up the numerical model of corrosion phenomenon. The k is stiffness coefficient by corrosion, the c is damping coefficient by corrosion and the μ is friction coefficient by corrosion. The results about each parameters are explained in this paper.ehicle. In 2013, the real seas experiment of MineRo was conducted and was discovered a damage of vehicle platform after the experiment.
