Biomechanical Modeling of Human Finger

Abstract:

Many of the studies in the biomechanics of the human body made globally focused primarily on hand-arm. This segment of the human body is considered a "gateway" of vibrations to other parts of the body or to internal organs. A long-term exposure to these mechanical vibration (caused by vibrating hand equipment: drill, grinder, etc.) affects the soft tissues and may lead to a dangerous syndrome, that is particularly vibration white finger (VWF), which is narrowing of blood vessels, a phenomenon that in time and untreated can even cause gangrene. This article focuses on a dynamic model with three degrees of freedom of the human finger. Some dynamic characteristics, such as centre of gravity, stiffness and damping, using both a rigid body structure system and computer simulations can be determined after measuring the vibrations.
