simulator for testing tribological wear hip implants of bones and joints. the invention relates to a simulator for driving in 3dof tribological wear tests on hip prostheses (p.t.h). this simulator is composed of three control units, data acquisition and data processing, and device to carry out the test itself.the control unit of the simulator consists of a start \/ stop system (1), a display of force (2), a temperature controller (3), a counter totaliseur cycle (4), a variable speed drive (5), a security system in the form of an emergency stop and status display the rod (6).the system is implemented in the housing (8) with a chain of acquisition and interface card. the loading unit is composed of a servo actuator (9) driven by a pump (7) interposed between two fixed plates (p1) and (p2) relative to the mobile guide defined by three columns (c1), (c2) and (c3).the movable shelf (p2) transports the cargo to flow through the module test set (p3) and the spring system (10) which plays a dual role. in fact, it helps to maintain contact between the head and the cup p.t.h, on the one hand, and, on the other hand, it makes the point in a cycle.the force sensor (11) is mounted in the vicinity of standard specimens test modules. the angulations in three degrees of freedom of the total hip replacement (p.t.h (flexion \/ extension, adduction \/ abduction, internal \/ external rotation) are carried out by a group of movement (rotation) to (14).an anti rotation device not shown can be due to the presence of the angles (23) at an angle of approximately defined in (14). the system is mounted in ac\u00e9tabulaire (12) and the head of p.t.h is set at the level of (20). the whole system p.t.h + head) is immersed in a biological solution at the cell level, maintained at constant temperature.Simulateur tribologique pour essais dusure des implants ostéoarticulaires de hanche.
