Numerical modeling and experimental estimates of structural member fatigue characteristics

Introduction. In the algorithm for predicting the resource of machine parts, models of external actions, fracture resistance, and temporal development of a particular type of damage to these units interact. The applied issues of the resistance of machine parts to fatigue failure are considered. The scientific research and regulatory materials are adapted to determine the characteristics of endurance to the specifics of structures and materials of the construction-and-road machinery and agricultural machinery. The work objective is to use the analysis of existing methods to develop recommendations for the calculated determination of the endurance parameters of structural members of the agricultural machines.Materials and Methods. The initial data were scientific studies on the fracture mechanics of the engineering materials and structures, as well as standards for endurance characterization methods. The need to test methods for determining fatigue characteristics to use them in the road construction machinery and agricultural machinery projects follows from the specifics of their designs, operation conditions and industry-specific range of materials...
