Method for Vehicle Body Structures
This project is concerned
with the use of optimization methods in the vehicle industry. Numerical
optimization has been used with limited extend in the vehicle industry.
However, great potential of using optimization methods has been identified
during the development process of vehicle body structures. One driving
force in this direction is the increased focus on building lighter and
cheaper vehicles with better crashworthiness. There is also an interest,
from an academic point of view in the area of optimization research, to
establish the use of optimization methods in the industry.
Below an overview of the design
method created in cooperation with Ph.D. student N. Bylund. This method is
the core for the project.
