Modelling and analysis of biological joints of a human arm in different movements

In the present work, irregular complex joints of the human arm are modelled in the computer-aided design environment. Accurately the geometric models of the joints and surrounding bony regions are developed from computed tomography data set and the range of movements are analysed. In this present work, biological joints are approximated into the mechanical joint without losing any kinematic behaviour and degrees of freedom. Then the analysis is done to determine the importance of joint geometries with different loading and boundary conditions. The present study helps to predict the behavior of joint configuration in the design stage.
