Nobutaka lto. Theoretical approach to the analysis of the forces acting on the wheel for farm use. Bull. Faculty of Agriculture, Mie University, No. 46, 149-198 (1974). In this report, a theoretical analysis of a powered wheel and an unpowered wheel of a wheel-type farm use vehicle under certain conditions is discussed. The calculations were made using the results obtained from photoelastic experiments to find the stress distribution pattern of the interface between the wheel tread and the road surface along the contact length of the tested rigid wheel. (Author's summary.) Nobutaka Ito. A study on the slip sinkage of the driven wheel for farm use vehicle. Bull. Faculty of Agriculture, Mie University, No. 46, 121-147 (1974). The slip sinkage phenomenon of the driven wheel of a tractor in steady state operation with a drawbar pull load has been largely solved with experimental data obtained during the tractor operation. This report focuses on the phenomenon of the slip sinkage of the driven wheel of the farm tractor. An experimental analysis is made of most important dynamic factors pertaining to the tractor wheel-soil-terrain relationship. This includes the following: (l) Relationship between the slip and the sinkage of the driven wheel with the drawbar pull load. (2) The transient reponse of the driven wheel sinkage phenomenon, which can be observed, is defined as the potential sinkage. (3) The relationship between the contact pressure of the tread, the contact length and the slip sinkage of the driwm wheel. (Author's summary.) 2.
