Stability Analysis and Modification of Guide Support System of Piston Rod in Labyrinth Reciprocating Compressor

摘要

Based on the characters that the piston rod of labyrinth reciprocating compressors is supported by a guide bearing system in the direction of movement, simplified mechanical model of piston rod is established. To determine the effect of relevant parameters on the vibration and stability of piston rod, modal analysis, harmonic analysis and buckling analysis are performed with ANSYS software. The Analysis result is used for the optimization of the guide support system of piston rod, and good result is obtained.
