Abstract

Crankshaft is the main part of reciprocating compressor. Its structure parameters influence the reliability and service life. In order to improve the reliability of the crankshaft, Finite Element Method (FEM) is applied for three-dimensional modeling and static strength analysis. The shaft model is established and imported into ANSYS, then imposed the appropriate constrains, and applied load. The stress of crankshaft journal under the maximum comprehensive piston force was obtained accordingly. In addition the main destruction form of crankshaft is torsion vibration. For this purpose, 6 model of the crankshaft was analyzed for reduce the deformation and torsional vibration based on Modal Analysis. They can provide a theoretical basis for the further design optimization of the crankshaft.
