ABSTRACT
This study presents a holistic analysis of radial shaft seals by means of 3D finite element analysis (FEA). Special emphasis is given to the sealing edge, examining its complex behavior under operating conditions, and including the surface roughness profile on the microscale for detailed 3D model simulation. In addition, the underlying equations of hyperelastic material models, which are important for appropriately simulating the elastomeric parts of the seal, are discussed to give a sound mathematical foundation to the simulations. This encompasses thorough discussions on boundary conditions and mathematical models necessary for replicating the complicated defor- mation and contact mechanics of the sealing interface. The tangential distortion of the sealing edge, an important factor determining sealing performance, is examined using multiscale models linking macroscopic seal geometry to microscopic surface roughness.
