Due to the complex working and storage environment for airplanes, the consumptive failures of airborne products are unavoidable. Aiming at the problem that degradation behaviors that cause this kind of failures are frequently neglected, based on the concept of degradation for airborne products, a new method of conducting research that treats aging process as a critical degradation behavior is presented. According to the characteristics of airborne mechano-electronic products, steering engine is defined as a critical airplane airborne mechano-electronic product. Through detailed analysis of the vulnerable area of steering engine, the failure mechanism of aging of steering engine rubber seal is discussed. The degradation model of steering engine rubber seal is presented. Finally, feasibility of the method that replaces the research of degradation behavior of the airborne mechano-electronic products with that of aging is verified.

A theoretical approach is described which overcomes the problems of convergence previously associated with obtaining solutions of the elastohydrodynamic equations for a reciprocating, rectangular section rubber seal. Convergence of this method is extremely rapid. Results are presented which illustrate that it is suitable both for instrokes and outstrokes at realistic sealed pressures. Experimental measurements of pressure distribution are presented for comparison.

This paper start with a discussion on various types of strain energy functions of rubber like materials. Theoretical analysis based on the strain energy function given in by Y.C.Gao in 1997 is proposed. The material parameters of strain energy function were curve-fitted from the uniaxial tensile test. The selected constitutive relation of rubber like materials was implemented into a finite element code MSC.Marc as a user material subroutine to analyze the thermal and mechanical behavior of rubber seal under the plane strain conditions. Contact force and distribution of the contact stress between lip seal and shaft are analyzed and coupled thermal mechanical analysis of rubber seal was proposed. The contact pressure distribution is readily obtainable from the nonlinear finite element analysis and the coupled thermal mechanical analyses results indicate that the thermal stress only have minor influence on the deformed shape of rubber seal, which will be a useful technique for predicting the properties of rubber seal and providing reference for engineering design. Keywords:rubber like materials, nonlinear finite element, contact analysis, thermal mechanical analysis
