Abstract
The authors analyze stresses and strains in elements of undercarriage steel constructions of heavy haulers and state the law of mathematical expectation of stress amplitude. The polynomial relation is set between specific energy input and mathematical expectation of stress amplitude. The maximum permissible operation conditions are found for heavy haulers based on criteria of energy intensity of blasted rock transportation and endurance of steel constructions of rear axle.
