Název v původním jazyce

Application of the Hertz´s Theory on the Analysis of Two Bodies in Contact

Popis výsledku v původním jazyce

The paper deals with the force elastostatic contact analysis of two bodies at a point in accordance of the Hertz?s contact stress theory. The complete set of assumptions, which directly or indirectly affecting the Hertz?s contact stress theory, is presented. The surfaces of given bodies which are dened by the vector functions are substituted at the contact point by approximate surfaces of the second degree and consequently there is determined the differential surface, surface of relative distance, of these second degree surfaces. On the basis of knowledge of principal normal curvatures and their directions of this differential surface is determinated the contact stress state, contact displacemetns and a contact surface after applied of a normal force at the contact point. The numerical solution of Hertz?s fundamental formulas and elliptic integrals is made by own algorithm. A geometrical visualisation of obtained results of this analysis is made.
