abstract

  • A numerical model of a roller bearing is presented in this paper. These simulations provide us with the spatial and time distributions of stress and strain values, as well as all the nodal
    displacements at every time step. The model was developed with the
    finite element method (FEM) for mechanical event simulations (MES) with
    the commercial code AlgorTM. The model has been validated by
    verifying that the contact force distributions correspond to those
    predicted by the analytical model of Harris&-Jones.As an
    application, a study of sliding between the rollers and the races has
    been carried out. For each roller, a rolling zone can be defined in
    which local sliding (computed between two consecutive time steps) is
    negligible. According to the simulations, we conclude that the rolling
    zone is practically the same for all the rollers in the same simulation;
    that this rolling zone is smaller than the corresponding load zone, and
    that rolling and load zones are angularly centered with respect to each
    other.
