ADVANCED SIMULATION OF AN ADAPTIVE LOWER LIMB PROSTHESIS Vom Fachbereich Maschinenbau an der Technischen Universität Darmstadt zur Erlangung des Grades eines Doktor-Ingenieurs (Dr.-Ing.) genehmigte D i s s e r t a t i o n vorgelegt von M.Sc. Nasim Alnu’man aus Amman, Jordanien Berichterstatter: Prof. Dr.-Ing. Holger Hanselka Mitberichterstatter: Prof. Dr. rer. nat. Michael Schäfer Tag der Einreichung: 21.01.2010 Tag der mündlichen Prüfung: 04.05.2010 Darmstadt 2010 D17 II Abstract The normal daily human activities include different levels of energy and strength needs, and this applies also for walking such that walking at high speeds needs more stiff muscles compared with walking slowly, and walking during carrying heavy loads or on inclined surfaces needs more energy than during doing the light housekeeping activities. For a healthy individual the human foot has already the ability to change its stiffness and to store and return a part of the elastic energy in a compliant structure of muscle fibres and series elastic elements. In the case of amputations in the lower limbs the amputated limbs are replaced with artificial limbs. A problem appears by this replacement that the new artificial limbs are designed to satisfy some described tasks and any change in these tasks or in the boundary conditions leads to an incompliance and unsatisfactory motion of the amputees.
