Abstract
Paper presents results and experimental stand of contact strains at dynamic
load. Grinded samples of nominal contact area 56,5 cm2 were subjected to investigations. For a given harmonic loads time functions of normal contact strains and their velocities were determined. The examined joint was appropriately modelled using FEM system ADINA. Applying an existing in the system model of the contact, characteristics (the same as in the experimental investigations) were determined. Comparing the experimental and computational results large discrepancies were observed. Therefore a thin intermediate layer was introduced to the computational model of the characteristic corresponding
to that determined on the basis of experimental investigations. Such modified computational model delivered characteristics that are in accordance with the experimental results.
