Dynamic Behavior of Crawler-Type Vehicles : The Experimental Examination of Straight Propelling

抄録

In the previous paper, we developed equations of motion for analyzing the dynamic behavior of crawler-type vehicles during straight propelling on soft ground and firm ground. In this study, experiments were carried out in order to verify the validity of the simulation model. The power shovel, a typical example of a crawler-type vehicle, was used in the tests. We measured the dynamic characteristics of the ground to determine the settlement and shear with consideration of hysteresis. The results of experimental tests are in good agreement with the theoretical results. The dynamic behavior of the vehicles, as indicated by parameters such as the dynamic ground pressure, is determined.
