Deep-Drawn U-Shaped Sheet Metal CAD Files Derived from NHTSA Crash Vehicles

<p>This dataset contains 90 U-shaped CAD geometries that are derived from the NHTSA crash vehicle simulation models. The geometries undergo a series of modifications:</p> <ul> <li>Shape Filtering: Select meshes suitable for deep drawing with a U-shaped profile.</li> <li>Duplicate Removal: Exclude symmetrical duplicates from vehicle structures.</li> <li>Boundary Representation Entity Definition: Place vertices on characteristic mesh features. Connect vertices with edges. Create faces from closed edge loops.</li> <li>Model Transformation: Orient models with drawing direction along -z, length along x, and width along y.</li> </ul> <p>The final CAD geometries represent the post-deep drawing state. Geometries are provided in neutral STEP format, each accompanied by an image. Further specifications are given in the associated publication(s).</p> <p>We want to thank the National Highway Traffic Safety Administration for providing the crash models and the allowance to publish a dataset. We want to inform users of the dataset that a sophisticated engineering evaluation has to be conducted whether the provided models should be used in crash simulation.</p>
