 Rubber O-Ring Against Stainless Steel Surface

Abstract

Abstract: The thermal characteristics of reciprocating friction of the nitrile rubber O-ring against stainless steel surface were successfully simulated by FEA (finite element analysis) and varified by experiments base on the Mooney-Rivlin model with high-order terms. The effects of reciprocating frequency, friction coefficient, contact pressure and ambient temperature on the temperature field of counterpart were investigated by using variable parameter method. Results showed that the FEA model could accurately analyze the characteristics of frictional heat generation at the rubber/metal friction interface. The temperature of the friction interface during the steady phase increased with increase of reciprocating frequency, friction coefficient and contact pressure. The temperature rise rate of the friction interface was independent of the initial ambient temperature. The stable value of the friction interface temperature had a linear relationship with the reciprocating frequency and had a positive parabolic relationship with the friction coefficient and the contact pressure. Zones close to the friction heat source had dense isotherms and great temperature gradient.
