نویسنده
چکیده
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.

متن کاملEnsuring High Reliability of Reciprocating Compressor with Ball Joint
Some reciprocating compressors have connecting rods with ball joints to join the crankshaft and the piston. The load of the pressurized gas inside the cylinder directly loads the joint of the piston and the connecting rod. For this reason, it needs to be highly reliable, so it needs to be made of hard material, high-precision spherical surfaces, and a complicated assembling line. Accordingly, t...
