Abstract: |
Reliability assessment of
reciprocating equipment piston rod leads to nonlinear elastic-plastic
deformation analysis of rod with initial imperfection under axial dynamic
load. In this paper a new and effective model and analytical simulation
method are presented to evaluate dynamic deformation and elastic-plastic
stress of reciprocating machine piston rod. This new method has capability to
account for geometric nonlinearity, elastic-plastic deformation and dynamic
effects. Proposed method can be used for evaluation of piston rod performance
for various reciprocating machines under various operation situations. Rod
load curves and maximum allowable rod load are calculated with presented
method for a reciprocating compressor. Useful recommendations and guidelines
for rod load, rod load reversal and rod drop monitoring are also addressed. |
