Numerical Analysis of Fatigue Degradation of Screw Pump
Original language description
In this article numerical analysis of fatigue damage of screw pump is discussed. The process of fatigue degradation of the screw is example of fatigue crack growth in notched bar under biaxial loading. This biaxial loading consists from axial tension loading and torsion for one screw systems and in the case of machines with several screws the loading consist from bending and torsion. The fatigue process was studied using computational methods. The screw pump used in this study were made from two different alloys and the effect of various surface layers on the fatigue resistance was also studied. The theoretical model is in a good agreement with experimental results.
