Evaluation of the Destructive Effect of an All-wheel Drive Vehicle to the Ground

Abstract

The article analyzes works, devotes to wheel influence on ground. Existing techniques do not consider slipping wheels and cannot estimate design of a car. The authors propose a parameter considering basic destroying factors (compaction and shifting of ground). The parameter considers increase of the total interaction area of a wheel with ground under curvilinear motion of a car. The analysis shows basic design vehicle features influence on track formation and calculation of harmful impact to a soil value under curvilinear car motion. Calculations show that the maximum harmful impact is observed under partial track overlapping.
