Abstract :
This paper presents a characterization of the axial vibrational behavior of a common hand-driller coupled to a three DOF HAS (Hand-Arm-System) model. The different components are represented as lumped masses and the connections between them with a spring and a damper. The elastic constant for the structural elements are determined using FEA (Finite Element Analysis) simulations, while the damping constant values used are the recommended by the Software 20-SIM for structural damping. Once the Bond-Graph model is developed, the equations that describe the vibrational behavior of the HandTool system can be obtained. The software 20-SIM is used to simulate the developed Bond-Graph model and to determine the Hand-Arm system vibrational response for a specific excitation force.
