Description of the research topic:
The motion of off-road vehicles is greatly influenced by the mechanical properties of the soil. The mobility of the vehicle is strongly affected by the load bearing capacity and sheer stress of the soil. The mechanical properties of a given soil are highly depending on the moisture content. For example it is easy to move on soils with low moisture content, and it is nearly impossible at high moisture content. The color of the soil is greatly influenced by the moisture content of the soil. The knowledge of the connection of the soil color and mechanical properties makes it possible to predict the vehicle mobility on terrain and to create a mobility map. The task of the candidate will be to investigate the connection of soil color and load bearing capacity. This is a pioneering research, which is in connection with the autonomous terrain vehicle concept.
The aim of the research work is to investigate the soil color-load bearing capacity-moisture content connection system:
1- Perform soil tests in the laboratory. Cone penetrometer device, bevameter, moisture content meter and HI-RES camera system will be used.
2- Experiments on various soil depths versus various diameter of plate of tester, soil density and soil moisture content.
3- Draw the curves that explain the relationship among the soil color-load bearing capacity-moisture content.
