AbstractBased on a classical approach for the determination of the integral characteristics of soil-vehicle interaction a problem of investigating the influence of geometry of the soil-tracked vehicle interface surface on drawbar pull is posed. The vehicle-soil interaction model of the process of local shear failure is considered. The problem is reduced to an isoperimetric task of the calculus of variations, a Lagrangian is constructed, and the functions involved in the Lagrangian are assessed. The profile of the track contact area providing a drawbar pull extremum under certain assumptions of forming tangential stresses in the contact area is produced.
