摘要:
为了研究气缸密封件的性能以及失效情况，运用有限元分析方法对格莱圈弹性体进行分析.利用有限元分析软件建立了格莱圈有限元分析模型，通过建模、划分网格、加载、求解以及后处理等步骤，对其在不同压缩率、不同气压时密封面接触压力分布规律进行探讨分析，确定格莱圈易失效位置，分析压缩率和气压对格莱圈密封面最大接触压力的影响.结果表明：在位移云图和接触压力云图中，格莱圈密封面最大接触压力随压缩率和气压的增加而增加；格莱圈的方型圈与缸套的接触压力最大，且最大接触压力明显大于通入气体的压力，故格莱圈不易失效；气缸在实际气压0.4 MPa和8%压缩率的情况下能正常工作，为评定缸阀一体化气缸的可靠性提供了参考.
Abstract:
To investigate the performance and the failure place of cylinder seals,the finite element analysis method was used to analyze Glyd sealing ring elastic and ANSYS was used to establish model of Glyd sealing ring.The distribution of the sealing surface contact stresses was discussed and the place of failure was determined in the different compression ratios and in the different gas pressures after modeling,meshing,loading,solving and postprocessing etc..The influences of compression ratios and gas pressures on the maximum contact stress were analyzed.The results show that the maximum contact pressure of Glyd ring sealing surface increases with the increase of compression ratio and gas pressure;the contact pressure reaches the maximum at interface of the cylinder liner and the square ring of Glyd，which is significantly greater than that of the gas，so the Glyd will not failure；the cylinder can work normally in the actual 0.4 MPa gas pressure and 8% compression ratio,which provides reference to assess the reliability of the cylinder valve integrated cylinder.
