Abstract: With regard to integrated structure parts, a new method, to
determine the relationship between displacement and characteristic curve
curvature, is approached. A new formula to be followed while correcting
the distorted parts is analyzed. Based on the analysis, the expression
for computing U section part’s reverse bending curvature in
corresponding to its original deformed curvature is obtained.
Elastic-plastic theory is applied in deducing the expression. For
operating convenience, a formula for accounting the reverse stroke of
pressing down is further given. To special aviation integrated structure
parts, connection curves are presented. The result reflected the
relation between the correcting curvature and the deformed parts’
original curvature, and the relation between the stroke of pressing down
and the original curvature. The examples show that the method presented
is practical.
