Summary

In this paper, a fatigue prediction of the reciprocating compressor was studied. The fatigue life of the LDT (Line Discharge Tube) situated in repeated load and the deformation was studied analytically and experimentally. Generally, there are two representative methods to predict the fatigue stress depending on the type of load. “Stress- Life scheme” can be applied to the problem which takes a lot of repeated stress within the elastic strain range. “Strain-Life scheme” can be used when it comes to the problem of low-cycle loading in the plastic strain range. In this paper, the Stress-Life scheme is used to predict fatigue life of LDT. Firstly, the analytical results verified using experimental method. Then, the relationships between design parameters and fatigue life were established using analytical model. Finally, the fatigue life design optimization of the LDT was progressed by means of the relationship.
