  text: Radial shaft sealing rings (RSSR) are important machine elements used in rotating
    and oil lubricated systems. Their main task is to prevent oil from exiting the
    system and dirt particles from entering the system. When this function is not
    fulfilled, a leakage can occur and cause excessive damage after certain operating
    times, such as gear failure due to insufficient lubrication. This is the reason
    for the high level of current research interest in seals. The sealing function
    of RSSR occurs in the contact area between the sealing lip and the shaft. The
    contact takes place over a very small contact width of approximately 1 μm.
    These extremely small dimensions and the complex relationships between the functional
    influencing variables on the radial shaft sealing system make it difficult to
    simulate wear on the sealing ring. The energetic consideration of the wear process
    offers the possibility of quantifying influencing variables more easily by their
    energetic contribution, which can be determined experimentally. Based on experimentally
    measured total friction moments, and with the help of a semi-analytical (SA) solid
    contact model based on the half-space theory, this paper presents a modelling
    approach for the calculation of wear at the sealing ring. The model presented
    in this work differs from the existing models in two ways. The first particularity
    is the coupling of SA method with finite element method (FEM) for the resolution
    of the contact between the sealing lip and the shaft, allowing a fine discretization
    of the contact zone (by SA method) and the consideration of the structural behavior
    (by FE method). The SA method compared to the commonly used FEM presents a great
    saving in computation time. The second particularity is the use of the real data
    obtained during the wear tests. Most existing simulation models are based purely
    on contact pressure. This means that through the contact pressure obtained by
    simulation and a given sliding distance value, a friction energy will be estimated
    which will be used in a next step using a wear model such as Archad’s to
    calculate the wear rate. In this publication the value of friction energy was
    obtained directly on an experimental basis and a more appropriate wear law, such
    as Fleischer’s, taking into account the friction conditions, was used to
    estimate the wear rate.
