Abstract
O-rings are seal structures widely applied in a variety of mechanical systems. In this paper, the time-dependent performances of O-rings are investigated with the aid of finite element (FEM) analysis. The investigation starts with a discussion on the failure mechanisms of O-ring seals and FEM models are built to establish relations between O-ring failures and the material properties. Since the material properties will degrade with time, we further investigate the influence of the degradation on the sealing performances of O-rings. The results show that the degradation of materials might be one reason for the time-dependent O-ring leakages and can be used to prevent O-rings from field failures.
