An original functional scheme of a mechanism for hip joint wear testing is herein presented. Characteristic lengths and angles are optimized with the purpose of simulating both kinematic and dynamics of human walking. In comparison with previous hip joint simulators the new one seems more simple and efficient. In fact the reproduced motion is no more only uniaxial, being able to imitate both flexion-extension and abduction-adduction rotation angles. As for dynamics, the three load components are simulated by adding a linear spring to the system. Feasible solutions are reached by evolutionary optimization strategy.

Abstract
An original functional scheme of a mechanism for hip joint wear testing is herein presented. Characteristic lengths and angles are optimized with the purpose of simulating both kinematic and dynamics of human walking. In comparison with previous hip joint simulators the new one seems more simple and efficient. In fact the reproduced motion is no more only uniaxial, being able to imitate both flexion-extension and abduction-adduction rotation angles. As for dynamics, the three load components are simulated by adding a linear spring to the system. Feasible solutions are reached by evolutionary optimization strategy.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
