Method for testing reciprocating seal wear life of O-shaped rubber seal ring

The invention discloses a method for testing reciprocating seal wear life of an O-shaped rubber seal ring, comprising the following steps of: step 1, testing material property of a seal element, wherein the material property test comprises a hardness test, a swelling test, and a friction coefficient test; step 2, performing a determination test on the life of the seal ring to obtain the cycle number when the seal ring fails, and determining the wear amount of the failed seal ring; and step 3, performing the parameter modification test of a sealing life model, obtaining the change law of the wear amount of the seal ring with time based on the dynamic seal wear life test, determining the detection step period of the parameter correction test based on failed cycle number, separately exploringthe speed and load to achieve the correction of the parameter K under different materials. 种橡胶制O形密封圈往复密封磨损寿命试验方法，其具体步骤如下：步骤，进行密封件的材料特性试验，材料特性试验包括硬度测试、溶胀测试和摩擦系数测试；步骤二，进行密封圈寿命确定试验，得到密封圈失效时的循环周期数，确定失效密封圈的磨损量；步骤三，进行密封圈寿命模型参数修正试验
