Nonlinear dynamic response of reciprocating compressor system wi...

In this paper, a nonlinear dynamic model of the single-stage reciprocating compressor system with a rub-impact fault.caused by subsidence is developed, considering the piston rod flexibility. Meanwhile, different rub-impact scenarios of the.crosshead including no corner, a single corner, two opposite corners, and two adjacent corners of the crosshead.impacting on the slide, are considered in this model. Numerical simulation results show that the subsidence, timevarying.load, and piston rod flexi
