Research on Lifetime Prediction of Engine Rubber Seal Based on Leakage Rate
In this study,taking the sealing structure of oil pump flanges as the research object,a rough peak contact model and a parallel flat plate leakage model are further established to calculate the leakage rate of the sealing surface based on the contact pressure distribution on the sealing surface obbtained by finite element mechanical analysis.At the same time,the time-temperature equivalent model of rubber performance is established by rubber accelerated aging test so as to predict rubber sealing life.Finally,the rubber sealing life is verified by seal leakage rate bench test,proving that the test result is basically consistent with the prediction result.
