Design and Implementation of Biomechanical Arm Kit

  • Hassan Fulaih Hassan, Dr. Sadiq J. Hamandi


The design and implementation of biomechanical arm kit simulation device is used to measure the tension and moment required to hold a weight at various angles for normal males and females, the purpose of the project was for biomechanical researches by making a model and applying the biomechanical experiment on it, which is called Occupational Biomechanics. In this project, the SOLIDWORKS program is used for the design, and for implementation, a European aluminium profile, aluminium profile interior corner, shaft and shaft holder, ball-bearing mount, protractor, weight holder and calibres, peek and rotator (custom-made), fishing cord, and electronic scale have been used, where the arms joined together by the shaft and its holder with the ball-bearing mount, the fishing cord represent the biceps muscle where it connected with the electronic scale which is attached to the forearm by the interior corner. The calibre is placed on the hand, which is the weight holder system, and the angle can be read from the protractor and the electronic scale reading represents the tension developed by the biceps muscle at this angle. This force developed by the muscle leads to pulling the attached forearm up and creates a moment at the elbow joint. The magnitude of the moment generated is the product of the muscle force or the reading of the electronic scale and the biceps moment arm.
