Finite element analysis of the swing-rod constraint reciprocating piston-type oil-free air compressor

摘要

Based on finite element analysis technology, a static simulation model of the swing-rod constraint reciprocating piston-type oil-free air compressor was established for stress analysis of the compressor. Simulation results show that the stress in the main parts of the new compressor is within the permitted range, so structure design and parameter setting of the compressor are reasonable. Moreover, the force condition of seal rings is improved by adding swinging-rod constraint mechanism, which will prolong the service life of seal rings. With this study, these simulation results will guide further modification and performance improvement of the compressor.
