题目：Development and verification of a one-step-model for the design
of flexible roll formed parts
摘要：The flexible roll forming process, developed atthe PtU in Darmstadt, enables the production of profiles
with a variable cross section lengthwise. This new forming
process   offers   high   flexibility   because   it   is   numerically
controlled. Proving the feasibility of each new geometry
requires either FE analyses or laboratory tests. To shorten
this time-consuming lay-out method, an analytic one-step-
model was developed. This model uses the results of FE
analyses and basic mechanical approaches as input data for
the lay-out of flanging processes. The input for the one-
step-model   consists   of   relevant   geometrical   and   material
data   to   specify   the   flexible   roll-formed   profile   and   to
perform therewith a quick feasibility check for new profile
geometries.
