Understanding the biomechanics of the forearm motion is essential for many research areas to improve the quality of human life. In this study, a new kinematic forearm model is proposed for estimating the rotation axis and obtaining proper forearm orientation during the pro/supination motion. As an improvement, a moving rotation axis is included as a link inside the model, and the rotation of the radius segment around the moving rotation axis is investigated. The model is tested in different motion patterns and compared with the rotation around tilted fixed axis as well as the experimental motion data. The outcome of the model shows that with defining the pro/supination motion as a rotation around the moving rotation axis (MRA), the trajectories and the range of motions of the radius are obtained within the expected ranges according to the literature. Besides, the MRA model provides more reliable results compared with the fixed axis. The comparison with the experimental analysis shows that the radius trajectory of the model is compatible with the motion data. For further investigations, with the subject specific adjustment, the proposed model can provide better understanding on the forearm kinematics.

DEVELOPMENT OF AN INTERFEROMETRIC TECHNIQUE TO BE USED IN MEASURING MICRON LEVEL CLEARANCES FILLED WITH A LUBRICANT Yildirim, Murat; Dursunkaya, Zafer; Okutucu Özyurt, Hanife Tuba (2009-10-21) The aim of this study is to develop an interferometric technique to measure micron level clearances occurring in small piston-cylinder arrangements; such as hermetically sealed compressors. A Cartesian model of the piston cylinder arrangement is manufactured and lateral and vertical motions are generated via a step motor, and micrometers, respectively, to simulate the piston motion and the change of clearance during the motion. Experiments are conducted in air and a lubricant. Measurements show the importan...
