摘　　要：针对轮式车辆在松软地面上的机动性问题,研究了轮胎地面附着特性的影响因素及变化规律,构建了包含加载速率及加载次数的基于土壤动态承载模型的车轮地面附着特性理论模型。本文首先通过土槽试验获取了在ABAQUS中搭建模型所需的土壤参数并明晰了加载速率和加载次数对土壤承载能力的影响,在现有的理论基础上构建了土壤动态承载模型;其次分析了车轮与地面的附着特性,在土壤动态承载模型基础上构建了以最大附着力为评估标准的车轮与地面的附着特性模型;最后在ABAQUS中选取Drucker-Prager模型来进行仿真并获得其最大应力和最大附着力来与理论值比较,从而验证本文提出理论模型的准确性。Aiming at the maneuverability of wheeled vehicles on soft ground,the influencing factors and changing rules of tire ground adhesion characteristics were studied,and a theoretical model of wheel ground adhesion characteristics based on soil dynamic bearing model was constructed with a certain moisture content including loading rate and loading times.In this paper,the effects of loading rate and loading times on soil bearing capacity were clarified through soil tank experiment,and a soil dynamic bearing model was established on the basis of existing theories.Secondly,the adhesion characteristics of the wheel and the ground are analyzed,and the maximum adhesion characteristics of the wheel and the ground are evaluated based on the dynamic load model of the soil.
