Abstract: A multi-purpose simulation
method for the roll-forming is proposed. The forming processes
of welded pipes are systematically simulated by using the
method. The three-dimensional curved surfaces of sheet metals in
forming processes are mathematically expressed by using the
shape function S(X) which represents flow pattern of each part
of sheet metal. Through optimizing the parameter n in S(X), the
best approximation of the deformation of sheet metal is derived
and the minimum power of deformation is obtained. A mathematical
procedure of this analysis is systematically formulated. The
simulation method can be applied to the analysis and simulation
for various roll-forming processes of welded pipes observed in
commercial production line.
