Tractive Performances of Wheel-Type Tractor (VI)

Theoretical Analysis of the Stress Distribution on the Lug Surface by the Soil

Abstract

To improve the performances of the running elements of the farm tractor on the paddy soft soil, the stress distributions in the soil near the rigid lug of the wheel were studied in conformity with M. G. Bekker's equation. The normal and shearing stress on the lug surface were accounted for from that results and the relations of stresses to the lug loads, shapes and the soil conditions were found by the theoretical analysis.
