Importance and aims of the research
Biomechanics science is interested in studying the dynamic function and the
movement of vital tissues depending on their mechanical properties.
The main objective of this research is to design a digital model of
the human femur
using the engineering software specialized in medical image processing and engineering
design in order to simulate the mechanical behavior. This would provide important medical
information to orthopedic surgeons concerning the paths and the causes of bone fractures
and deformities, and open a new perspectives in prosthetics efficiency enhancement.
Materials and methods
A three dimensional digital model of the femur was produced using the software
DeVIDE v 9.8 for medical image processing. A surface triangular mesh was constructed
and the mechanical response of the model has been simulated using Ansys 14.5.
Results and discussions
We have shown the steps necessary to design a computerized model of femur bone
on the basis of three-dimensional X-ray images. The results showed the distribution of
stresses and displacements of human femur at normal load conditions.
Conclusion and recommendations
It is recommended to adopt the specialized engineering software for the threedimensional
simulation which can be used in different medical applications.
This paper deals with computer simulation methods when constructing the
equipment in iron rolling mill plants for dimensioning machines, which have become more
important in the recent years. And it determines the ideal prerequisites to simulate dri
ving
system for electrical and mechanical subsystems. The drive systems is built around several
components which have their own technology and multiple time-scales: electrical
machines, power semiconductor, control circuits from the firing sequences to the different
regulators. This requires the simulation of both the electrical and mechanical components
in one model. The use of a uniform simulation program offers the possibility to combine in
mechanical modeling with the electrical necessities. This research will be in the description
of the simulation-aided design and its relationship with vibration caused by the twisting
torque using the drive systems.
