Mechanická analýza styku hlavičky a jamky totální endoprotézy kyčelního kloubu

Popis výsledku v původním jazyce

The paper belongs to biomechanics of a hip joint section. It is engaged in problems with industrial tolerances as one of the possible total hip prothesis insufficiency. Three computation models of the ball head and acetabular fossa were made, on which interference or clearance fit were simulated. Two computation models were 2D, from which one involve pelvis os and one was 3D. Real loading conditions of the hip joint during the slow walk of a human were simulated. Ascertained were values of contact pressses and frictional moment needed to turn ball head in acetabular fossa. Finite element method (FEM) system ANSYS was used to computation. On 2D solution on model of the ball head and acetabular fossa was verified that industrial tolerances have big effect on values of contact pressure and its distribution and also on value of frictional moment, needed to turn the ball head in acetabular. It can be definitely said that from aspect of value and distribution of contact pressure and value of
