The Seal Reliability Analysis of Oring Seals

摘要：

First, the seal reliability function of the Oring, that is the maximum contact stress between O-ring and plunger must be greater than the fluid pressure,is established, then on the basis of the nonlinear constitutive equation Mooney-Rivlin of rubber material, the finite element model of the O-ring is built using commercial software ABAQUS, according to the finite element model, the distribution fitting and test of the maximum contact stress of the O-ring is done,on the basis of which, the seal reliability index of the O-ring is derived.At last, the effect analysis of the variation of the design parameters on the reliability index is done.The method put forward in this paper would save a lot of test cost,providing a useful tool for valve designers.
