    two partners can be determined using experimental or numerical methods. For the
    validation of numerical simulations, appropriate experiments and material models

    be used in experiments to detect the area of contact between contact partners.
    A simplified linear-elastic material model of paper for compression in the thickness

  text: Regarding the increasing demand in seal lifetime and energy efficiency, a
    detailed microscopic simulation is necessary—as an addition to experimental investigations—to
    better understand and improve radial shaft seals. For this purpose, typically
    thermoelastohydrodynamic lubrication (TEHL) simulations are used. The published
    models range from rather simple elastohydrodynamic lubrication (EHL) models to
    very sophisticated TEHL models. Only very few models take into account the roughness
    or microstructure of both contact surfaces, though, since this would require the
    consideration of transient effects. In this article, a transient TEHL model for
    the contact of radial shaft seals is presented. Studies of the sealing contact
    are conducted, and the possibility of investigating shaft microstructuring is
    shown.

  text: In oil-lubricated worm gears, all moving components cause power losses during
    operation. These losses depend, among other things, on the viscosity of the lubricant
    used, which in turn is determined by the temperature present in the gearbox. The
    dependency between the temperature and the power dissipation is mutual, and they
    influence each other. For the analysis of gearboxes under transient conditions,
    the relationship among operating conditions, power dissipation, and temperature
    must be considered. In this paper, a method for the analysis of these interrelationships
    is presented, which is based on the combination of tribological simulation and
    thermal networks. With the developed calculation model, the gearbox efficiency
    and the temperature over time can be estimated for arbitrary load cases. The calculation
    results are compared with measurements on a real gearbox.
