摘    要:提出一种能自行跨越宽沟槽的八轮行走机构,为确定其越障及越壕能力,在简化力学模型的基础上进行理论推导,分析行走机构尺寸参数与最大越障高度及越壕宽度的关系,并重点分析车轮与接触地面间的附着系数与行走机构越障和越壕能力的关系,从而推导出该新型行走机构可以越过的最大垂直障碍高度,以及可以跨越的最大壕沟宽度.

关 键 词:八轮驱动  行走机构  越障越壕能力

Abstract:In order to determine the ability of overcoming obstacles and trenches of a walking device which can across wide trenches,this paper derives the mathematical theory on the basis of simplified mechanical model and analyzes the relations between the various parameters of the walking device and the maximum obstacle height and width.Especially,this paper analyzes the relation between the adhesion coefficient of the wheels to the ground and the ability of overcoming obstacles and trenches of this walking device.Then derives the maximum vertical obstacle and the maximum width of the trench this new walking device can overcoming are derived.
Keywords:eight-wheel driven  mobility device  ability of overcoming obstacles and trenches
