Requirements for static and fatigue strength of beams front axle of a truck

Abstract

Based on the results of road tests of the stress-strain state of the beam of the controlled bridge of a dump truck, recommendations for its design were developed. The most loaded zones of the beam under operating conditions have been identified. The safety margins of the bridge beam in bending and torsion, the ratio of the moments of resistance to bending in the vertical and horizontal planes have been determined. The test mode and the standard of the bench fatigue life of the bridge beam have been established.
