| 摘 要： | The O-ring in the rotary dynamic sealing system of gas meters should have outstanding long-term sealing performance under the conditions of high and low temperature,which can ensure thesafety of gas meters. In this paper,based on the O-ring sealing mechanism,taking the compression setas the main sealing index, a finite element simulation method is used to analyze the failure charac-teristics under different conditions according to the constitutive relation of nitrile rubber. Then,usingthe orthog...
