| 초록 |
In this study, a wheel test bed experimental setup is established in order to investigate the contact phenomenon between a wheel and a sandy road. Meanwhile, the discrete element method(DEM) is used to analyze the dynamic behavior of a rigid wheel driving on a sandy road. A contact method is developed between a rigid wheel and numerous particles. The longitudinal force and vertical force acting on the wheel are measured by using a 6-component load cell, and the wheel sinkage is measured by using a high - speed camera. The results of the simulation showed a good agreement with the experiments. |
