A Direct Toolpath Constructive Design Method for Controllable Porous Structure Configuration with a TSP-based Sequence Planning Determination

The inherent capabilities of additive manufacturing(AM)to fabricate porous lattice structures with controllable structural and functional properties have raised interest in the design methods for the production of extremely in-tricate internal geometries.Current popular methods of porous lattice structure design still follow the traditional flow,which mainly consists of computer-aided design(CAD)model construction,STereoLithography(STL)model conversion,slicing model acquisition,and toolpath configuration,which causes a loss of accuracy and manufac-turability uncertainty in AM preparation stages.Moreover,toolpath configuration relies on a knowledge-based approach summarized by expert systems.In this process,geometrical construction information is always ignored when a CAD model is created or constructed.To fully use this geometrical information,avoid accuracy loss and ensure qualified manufacturability of porous lattice structures,this paper proposes a novel toolpath-based con-structive design method to directly generate toolpath printing file of parametric and controllable porous lattice structures to facilitate model data exchange during the AM preparation stages.To optimize the laser jumping route between lattice cells,we use a hybrid travelling salesman problem(TSP)solver to determine the laser jumping points on contour scans.Four kinds of laser jumping orders are calculated and compared to select a minimal laser jumping route for sequence planning inside lattice cells.Hence,the proposed method can achieve high-precision lattice printing and avoid computational consumption in model conversion stages from a geomet-rical view.The optical metallographic images show that the shape accuracy of lattice patterns can be guaranteed.The existence of“grain boundaries”brought about by the multi-contour scanning strategy may lead to different mechanical properties.

创建行动导向下美丽乡村联创联建的规划设计方法探索

伴随着浙江省乡村发展愿景从“千万工程”到“美丽乡村”再到共同富裕的纵深推进,以单个行政村为单元的美丽乡村创建模式已经难以适应新的发展诉求。基于自然资源禀赋或基础设施地理空间连续性的美丽乡村联创联建工作,是破解各行政村独立发展的多重瓶颈的创新性尝试。针对具有明确的目标、资金、时间约束的美丽乡村创建行动,基于“产业-空间协同发展”的总体思路,试图探讨一种面向美丽乡村联创联建的规划设计方法,即“二阶三心法”。这一方法从乡村地区的存量资源切入,旨在系统性、创造性地回应创建行动目标,开展面向产业-空间复合型目标的空间规划干预:一是基于“土地矛盾最小化原则”进行空间节点设计,二是基于“空间投入-融合效益最大化原则”形成特色主线,三是基于“优先塑造-示范带动原则”打造示范样板。进一步的,结合湖州市道场乡菰城片区规划设计工作,探讨了该方法在产业策划和空间设计层面落地应用的关键问题和解决策略,为中国先发地区美丽乡村联创联建的规划设计工作提供经验借鉴。
