| Abstract | This study presents the results of measurement of tractive performance of a free rolling tyred wheel moving on two kinds of dry soft soil (sand and clay). The soil displacement pattern at 0.18 m/s forward speed was also measured. The traction parameters (towing force, skid and sinkage) for two soils at the different load (133.81 N, 267.54 N and 445.57 N) were quite similar and compared reasonably well with theoretical predictions. When the wheel was moving, the soil deformed in both horizontal and vertical directions over a wide area. It was moved in the horizontal direction more than the vertical direction and the sandy soil deformed more than clay soil at particular load, When the load was greater the deformation was also greater in all directions. The soil displacement patterns under the wheel could be classified into four regions. 1. soil close to the wheel surface. This was moved forwards and compressed in both horizontal and vertical directions. 2. Soil under the wheel. This was expanded in the horizontal. direction and compressed in the vertical direction. 3. Soil in front of the wheel. This was moved forwards, expanded in the vertical direction and compressed in the horizontal direction. 4. Soil behind the wheel. This expanded a little in the vertical direction and compressed a little in the horizonal direction after the wheel had passed. |
