OSU-Honda automobile hood dataset (CarHoods10k)

The CarHoods10k data set comprises a set of over 10,000 3D mesh geometries for variants of car hood frames, generated through an automated, industry-grade Computer Aided Design (CAD) workflow described in Ramnath (2019). The data set provides realistic designs that were validated by experts with respect to realism, manufacturability, variability, and performance. Variations in geometries were generated by a feature-based approach that varies parameter values describing design features on 109 parameterized base geometries ('skins'). Parameters describe feature patterns such as cut-outs or ribs on the hood frame as well as their properties, for example, rib location and height, or cut-out location. Geometries are represented as surface meshes (STL files) and are provided with the corresponding design parameter values and performance metrics from structural mechanics, generated through finite element analysis (FEA). The data set provides realistic and validated designs for the evaluation a...

CarHoods10k数据集包含超过10000款汽车引擎盖框架变体的三维网格几何模型，其生成流程采用Ramnath（2019）中所述的自动化工业级计算机辅助设计（Computer Aided Design, CAD）工作流。本数据集提供经专家从真实性、可制造性、多样性与性能四个维度验证的写实设计方案。几何模型的变体通过基于特征的方法生成：该方法通过调整109个参数化基础几何模型（称为“蒙皮（skins）”）上的设计特征对应参数值，实现多样的几何变体。这些参数用于描述引擎盖框架上的特征样式（如切口或加强筋）及其属性，例如加强筋的位置与高度、切口的位置等。所有几何模型均以表面网格（STL文件）形式存储，并附带通过有限元分析（Finite Element Analysis, FEA）得到的结构力学性能指标与对应的设计参数值。本数据集可提供经过验证的写实设计方案，用于……的评估。
