Abstract
Infant shaking can cause serious damage (inflicted head injury by shaking trauma), it’s occurrence indicates the necessity for infant protection. To ensure reliable jurisprudence, it is important to know the exact consequences of shaking on an infant’s body. These consequences can be researched by the use of an anthropomorphic shake doll. With this doll, shake experiments can be performed in order to better understand the kinematics of the body and body parts during shaking. This study aims to establish design criteria for this doll as well as designing, producing and testing the joints for this model. A requirement list is presented, as well as a design for a joint that can be used for the limbs of the doll. To ensure structural integrity of this design, a representation of the joint was created and an indicative mechanical shake test was performed. Building further on this, real life prototypes have been made.
