Abstrakt: In modern, ever-changing markets, product redesign is an essential means to keep a company's competitive advantages in business. In this paper, we propose a new approach to streamline the redesigned workflow of thin-walled products by means of geometric reverse engineering (RE), isogeometric shell analysis, and Tspline surface (T-splines) modeling. Firstly, we apply RE technique to create a computer-aided design (CAD) model from one physical thin-walled product. Then, we convert this CAD model into mechanical T-splines (MT-splines), which are built on the T-splines and isogeometric shell analysis. MT-splines not only can achieve the direct mechanical analysis of redesigned products in computer-aided engineering (CAE) by skipping the costly meshing process but also possess the flexible shape editability that comes from the combination of geometric alteration and mechanical deformation, all of which considerably improve the efficiency of product redesign workflow. Additionally, we study and find a helpful connection between local-uniform refinement (LU-Refinement) of T-splines and isogeometric analysis (IGA) in this paper so that we can always ensure the analysis-suitability of locally-refined MT-splines, which is crucial to the mechanical deformation and analysis of MT-splines driven by IGA. Finally, two redesign examples of bike mudguard and car-door are provided to demonstrate the usefulness and effectiveness of our proposed redesign workflow, offering new thinking for integrating RE, CAD, and CAE in new product development.
