What Is the Digital Modeling Process for Complex UHPC Shapes? Qinglong UHPC Digital Design Technology System

Digital modeling of complex UHPC forms adopts a full-process digital solution of "reverse scanning + parametric design + BIM collaboration". First, 3D laser scanning is used to obtain point cloud data of the existing structure (accuracy up to ±1mm), then Rhino+Grasshopper is used for parametric modeling, and finally the model is imported into the BIM platform for clash detection and component optimization. The entire process achieves seamless integration from concept design to fabrication, keeping design errors within ±2mm.

In an art center project, designers completed the sculptural form design using ZBrush, optimized the mesh with Geomagic Wrap, and then performed structural form-finding analysis with CATIA. Qinglong UHPC uses five-axis CNC machining centers to directly output machining codes, achieving precise fabrication of complex double-curved components. The entire process shortened the construction period by 40% and reduced material waste by 25% compared with traditional methods.

3D Data Acquisition Technology

Laser scanners are used to obtain point cloud data with a point spacing ≤1mm. Photogrammetry supplements the details with an accuracy of 0.1mm. Point cloud data quality standards are established to ensure the accuracy of subsequent modeling.

Parametric Modeling Process

Parametric models are built using Rhino+Grasshopper, with key parameters including curvature radius, panel thickness, stiffening rib layout, etc. Algorithms generate optimized structures, achieving optimal material distribution.

Structural Performance Simulation

Finite element analysis software is used to verify mechanical performance, including static analysis, wind load simulation, seismic calculation, etc. Iterative optimization ensures the structural safety of artistic forms.

Machining Data Output

Five-axis machining codes are exported directly, achieving design-manufacturing integration. The machining data includes mold surface precision requirements, ensuring forming quality meets design standards.

Digital modeling is the foundation for realizing complex UHPC forms. Through advanced technical means, artistic creativity is precisely transformed into physical components.
