In order to investigate the mobility and the tractive performance of a wheel-type tractor, the deformation of soils beneath a wheel has been analyzed by the finite element method in this series of reports, taking account of the friction between a wheel and soils. In the Part I of the serial reports, the wheel was assumed to be a rigid body. In this report, considering the deflection of the tire, wheel was assumed, as an elastic model which is composed of the rigid rim and a number of the rigid rim and a number of springs in stalled radially to the rim. Further, soils are assumed to be a Hookean elastic body. Then, soil deformations beneath the wheel which undergoes a linkage and/or a slip were analyzed by the finite element method. The calculated results showed a fairly well agreement with experimental data obtained by the small soil bin test.
