- 論文の詳細を見る
Ultrasonic techniques were developed to study the characteristics for contact mechanics of an artificial hip joint. Total Hip Replacement model was used to determine contact pressure distribution on an artificial aceptabular cup subjected to compressive load ranged from 196 N to 588 N in four femur positions. The contact pressure was found to be non-uniform and reaches more than 6 MPa. It was shown that the tendency of the pressure distribution is in agreement with that obtained by the computer simulation. Some preliminary results were also presented to illustrate the effect of the direction and the magnitude of the load applied to a femoral head on the contact pressure distribution on the aceptabular cup and to evaluate the contact mechanism of the artificial hip joint.
