However, existing designs are mostly uniform, despite the potential benefits of non-uniform configurations. Non-uniform design involves variables from different levels, including number, position, and thickness of stiffeners, yet it has not been systematically studied. When attempting to obtain optimized designs, we found that existing methods formulate the problem as a mixed-integer bilevel optimization, which suffers from low efficiency. To address this, we propose a unified optimization method that transforms the bilevel problem into a single-level problem. Specifically, the panel is discretized using equidistant nodes, each assigned a unified design variable, and stiffeners are constructed by connecting activated nodes. This approach enables efficient optimization of non-uniform configurations. To validate the method, we conducted multi-objective optimization on triangular and trapezoidal corrugated cores under static out-of-plane pressure and dynamic planar compression. The results demonstrate that non-uniform designs achieve superior performance compared to uniform configurations. Furthermore, compared to the baseline bilevel optimization method, our approach achieves a higher hypervolume under the same evaluation budget, making it more efficient for designers to rapidly obtain optimized configurations.</div></div>","PeriodicalId":50866,"journal":{"name":"Advances in Engineering Software","volume":"205 ","pages":"Article 103918"},"PeriodicalIF":4.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143645100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although commercial CAM software can predict the macro-topography of a machined surface, incorporating the cutter edge geometry and its rotational movement is essential for accurately predicting the surface's micro-topography. In this work, three alternative algorithms based on the Z-Map method are proposed: (1) a parallelized version of Z-Map (MOD1) for increased computational efficiency, (2) a swept surface technique (MOD2) for more accurate simulations, and (3) a rounding technique (MOD3) for rapid, precise topography prediction by aligning cutter edge points. The user can choose one of the three algorithms based on computational resources and preferences.

The hybrid algorithm leverages the strengths of global and gradient-based optimization methods by combining Adaptive Simulated Annealing and Non-Linear Programming by Quadratic Lagrangian (ASA-NLPQL). The effectiveness of the ASA-NLPQL hybrid algorithm is validated through two numerical function examples and an engineering optimization case study, and it is subsequently applied to a real-world case study focused on the lightweight optimization design of an automotive seat skeleton. Firstly, the finite element model for modal analysis of the entire front seat skeleton of a passenger car is developed and validated through experimental tests. Key design variables are identified via sensitivity analysis to guide the optimization process. Subsequently, a surrogate model is constructed using sample points generated by optimal Latin hypercube sampling. The combined optimization strategy, based on the surrogate model and hybrid algorithm, is then applied to the optimal design of the passenger car seat skeleton. Optimization results demonstrate a 22.3% reduction in seat weight with negligible impact on vibration performance. Finally, the optimized seat skeleton undergoes various strength tests, with the results confirming that it meets the required strength criteria.

The proposed method automatically and accurately extracts table data from scientific literature without relying on table grid lines, thereby overcoming the drawbacks of existing technology for extracting data from three-line tables.
