To help researchers optimize the design of hip prostheses, the Bionix® 12-Station Hip Wear Simulator accurately simulates the motions, loads and environments experienced by the hip joint during walking.
Specifically, the system enables component optimization and material properties characterization. Features include a multistation configuration that tests up to twelve hip prostheses simultaneously.
It is designed for nominal operation at approximate walking cycle speed. Individual servohydraulic actuators are each attached to a mounting block inclined at 23° from vertical to match the approximate anatomical position of the hip joint. The inclined block and actuators, while axially loaded, are rotated to provide an exaggerated biaxial rocking motion that simulates walking kinematics.
Special corrosion-resistant fluid chambers house the acetabulum cup or femoral ball, and are designed to be filled with blood serum or saline solution.
