Wear prediction of double lip seal in lubricated condition
In order to accurately predict the wear of double lip oil seal,the axisymmetric and three-dimensional models of the oil seal were established using ABAQUS finite element software.The contact pressure distribution and wear profile of the main lip after wear were analyzed.The simulation results show that the contact pressure at the tip of the lip is the largest and gradually decreases on both sides;with the increase of wear time,the contact width shows an extending trend;the corresponding average contact pressure shows a downward trend with the increase of wear time.Accordingly,with the increase of wear time,the overall contact pressure of the lip decreases,which is even greater than the safe design pressure.It indicates that the lip seal still has reliable sealing performance.These results provide good reference value for evaluating the seal reliability and service life of lip seal.
