Finite Element Analysis on Vibration Modes of Femur Bone
نویسندگان
چکیده
Femur bone is the longest and largest bone found in human body. It is also one of the most commonly fractured bones of human body, especially for the elderly. In this paper, vibration analysis of femur bone is studied by the help of finite element simulation to provide more insight in designing bio-aided equipments or protective sports equipments for femur. The simulations were performed using the software – Abaqus. The vibration patterns for first twenty modes were studied. The mode shapes show that the natural frequency of vibration varies from 722 Hz to 8480 Hz. The results were compared with experimental results presented in literature. External excitation on the femur bone must be avoided to coincide with these natural frequencies; otherwise it could lead to fracture of bone.
