Abstract
According to the method described in the former report, stresses in a wheel disc produced, as a new attempt, were calculated and compared with the experimental results and the other simple calculations. The stresses due to the force fit of axle and the strinkage fit of tyre are considerably large and the type of spherical shell is especially disadvantageous, as it causes very large bending stress. For the axle load, the calculated value of stresses, assuming the rigid rim and tyre does not agree with the experimental value which is concentrated in the direction of loading. But, the stresses due to the axle load will be small even if the load is unequally distributed to each disc. On the contrary, the assumption is reasonable for the side thrust and the calculated values of stresses agree with the experimental result. As the stresses due to axle load and side thrust are superimposed in the inner side disc, the design is desirable in which the axle load is supported mostly by the outer disc.
