Abstract
The lubrication and sealing mechanism of elastomeric radial lip seals are significantly influenced by local deformations in the contact area between the sealing edge and the shaft. These microscopic mechanical effects cannot be completely analysed in visual observations. This paper presents a methodology for the numerical analysis of the radial compression and the tangential distortion of the sealing edge surface during operation. The finite element analysis is used for this purpose. The modelling of a three-dimensional multiscale model is described in detail. Results are presented and discussed with reference to the possible sealing behaviour
