Název v původním jazyce

Finite element model of fatigue fracture of reciprocating screw in moulding machine

Popis výsledku v původním jazyce

This work is devote to the study of fatigue degradation of some parts of moulding machine. The mechanical part of the moulding machine represents the mechanism which injects the molten plastic into the mould. The finite element analysis of fatigue damage of reciprocating screw, i.e screw pump is discussed and compared with results obtained from fractographical analysis of damaged parts of real machine. The process of crack growth in reciprocating screw is example of fatigue of notched bar under biaxial loading. For description of biaxial loading were selected methods based on Smith–Watson–Topper and Fatemi-Socie fatigue criteria. The reciprocating screw used in this study were made from two different steels (P20+Ni and H-13 steel). The theoretical model is in a good agreement with experimental results.
