Document Type and Number:
WIPO Patent Application WO/2022/179097
Kind Code:
A1
Abstract:
Disclosed in the present invention is a method for automatically constructing an editable model of an isogeometric topology optimization result. The method addresses the problem of three-dimensional isogeometric topology optimization, and performs quick and efficient post-processing on a three-dimensional isogeometric topology optimization result, so as to achieve the aim of automatically constructing a result model thereof and the aim of the result model being editable. According to the method, design variables are taken as high-dimensional coordinates of a control point, spline surfaces represented by control points of the three-dimensional isogeometric topology optimization result are extracted in a layered manner, and lofting is performed on top contours of the spline surfaces, such that the steps of constructing an isogeometric topology optimization model are simplified. According to the present invention, a geometric model is directly constructed according to the isogeometric topology optimization result, and the automatically constructed model has the advantages of being selectable and editable.
