Abstract
Recently, hip pads to prevent the femur fracture by falling have been developed for aged persons. It is necessary for hip pads that the material and the structure select and design to realize the higher performance of impact absorption. In this work, an experimental system was made to test the impact absorbing properties of eight commercial hip pads. Using an artificial femur with composite materials that composed of cortical and cancellous region, impact load was applied to greater trochanter of the femoral model. Impact absorbing performance was evaluated by the impulsive force, collision time and impact strain. As a result, a hip pad with hard shell showed the best absorbing performance in eight specimens.
