Abstract:
In this paper the finite element analysis for the swing body of
sheet metal straightening machine with 13 rollers is firstly discussed,
then the swing body is designed with the method of structure optimal
design. The results show that the weight after optimum is decreased by
1/3. By selecting materials automatienly in the optimal process the
whole structure can be composed of common steel plates, ensuring enough
strength, sufficient stiffness and the local weight of the swing body.
Key words:
