COMPUTATIONAL-EXPERIMENTAL STUDY OF CONTACT INTERACTION OF BODIES WITH NEARLY FORM SURFACES

In many constructions, their elements are in contact with nominally matching (congruent) surfaces. reality, this is disturbed due to deviations the shape of these surfaces from nominal. To study effect perturbation on distribution pressure, analysis stress-strain state body system punched sheet-die carried out. The middle element deviates flat shape. This causes a change pressure distribution. proportionality between clamping force and level also lost. reliability accuracy results obtained by numerical calculation have been experimentally confirmed.
