A MODE-BASED ELASTOHYDRODYNAMIC FORMULATION EMPLOYING LOW MODULUS HYPERELASTIC MATERIAL MODELS

摘要

This paper presents a mode-based elastohydrodynamic formulation employing low-modulus hyperelastic material models which exhibit strongly non-linear load-deflection characteristics. The mode-based method is applied to a reciprocating liquid O-ring seal, where it is found under steady axial motion that a relatively small set of modes captures the essential features of seal deformation when compared with that obtained with standard node-based methods.
