| Outline of Final Research Achievements |
In this research project, a comprehensive wheel test apparatus that employs an in-wheel sensor system and a particle image velocimetry technique has been developed. The test bed achieves a precise observation of wheel-soil interaction mechanics including wheel pressure, wheel sinkage, soil flow, and wheel dynamic behavior, which were not well clarified by classical experimental approaches. This research also proposed a method that provides the most feasible wheel size for off-road traction. The method finds a wheel radius and width that maximizes wheel traction performance, with less computational cost. These outcomes were presented in more than twenty five papers/books (incl. domestic conference) and in an invited talk at an international conference.
