A dynamics model of the tyre-ground system is the key in its simulation and should be as close to the real working conditions as possible. Based on the Discrete Element Method (DEM), a model of granule tyre and granule ground is built, and the complicated dynamic problems of vehicle driving are solved. The accuracy of the model is verified through calculating a number of parameters in the vehicle-ground system. So far, there is no effective method to simulate the earth sinkage caused by the tyre slip. With the above mentioned model, the sandy soil sinkage caused by the slip of the resilient tyre on it is calculated, and the results agree well with experimental data. The model can be effectively used in the study and calculation of the slip rate, the earth sinkage property and the relationships between vehicle and ground., authors=null, authorsList=null,

articleAbstract=探究轮胎-地面系统的动力学特性，建立更接近轮胎-地面系统实际工作状况的动力学模型是车辆行驶理论的核心问题之一。本研究运用颗粒-车辆地面散体动力学模型，针对目前车辆地面力学中，尚无有效方法对因车轮滑转导致土壤沉陷的问题进行模拟和计算的现状，采取相应的试验数据，建立相同的计算环境，对弹性车轮在沙地上因滑转引起的沙土沉陷问题进行计算，与试验结果进行对比分析表明有很好的一致性。该模型能有效地用于车辆地面力学中滑转率、土壤沉陷特性及两者相互关系的研究和计算。,
