What Is the Digital Modeling Process for Complex UHPC Shapes? Qinglong's Full-Process Digital Solution and Practical Verification

Digital modeling of complex UHPC forms is the core step in bringing creative designs to life, requiring a standardized four-step process of "data acquisition – parametric modeling – structural optimization – mold conversion" to achieve the unity of artistic creativity and engineering feasibility. Leveraging 28 years of digital R&D experience, Qinglong Group applies core tools such as Rhino+Grasshopper and BIM to achieve modeling precision of ≤±0.5mm and shape fidelity of over 99% in complex projects including the Shanghai Astronomy Museum and the Guangxi New Media Center.

1. Data Acquisition and Preliminary Preparation: Precisely Capturing Basic Form Information

Creative interpretation and parameter extraction: Aligning with designers' requirements to extract core form parameters (such as double-curved surface curvature, hollow-out patterns, and dimension ranges) and establish a basic data framework. Qinglong's designer team can quickly deconstruct abstract concepts and convert them into quantifiable modeling parameters. 3D scanning acquisition (suitable for replicating irregular shapes): 3D laser scanning of physical models or existing building components to obtain point cloud data with scanning precision of ≤±0.1mm. In Qinglong's 3-meter-high sculpture project for the Shanghai Astronomy Museum, scanning enabled a precise 1:1 replication of the form. Environmental data integration: Importing environmental data such as building facades and installation nodes to ensure the model matches the actual installation scenario. Qinglong uses BIM technology to integrate overall project data and prevent conflicts between the form and surrounding structures.

2. Parametric Modeling: Achieving Precise Construction of Complex Forms

Basic form construction: Using Rhino software to build 3D base forms. For complex structures such as double-curved and twisted shapes, NURBS surface technology ensures smooth lines. In Qinglong's double-curved panel modeling for the Guangxi New Media Center, the minimum radius of curvature was precisely controlled at 300mm. Parametric optimization: Writing algorithms with the Grasshopper plugin to achieve parametric-driven design, allowing rapid adjustment of dimensions, curvature, hollow-out density, and more. In Qinglong's hollow-out panel project for the Ouargla Hotel in Algeria, algorithms optimized the hollow-out patterns and improved production feasibility. Detailed design refinement: Adding details such as textures, reliefs, and joint seams to ensure form completeness. In Qinglong's wood-grain translucent panel modeling for Shanghai New World, tree bark textures were accurately reproduced, with light guide rod mounting hole position errors of ≤±0.3mm.

3. Structural Optimization and Feasibility Verification: Balancing Aesthetics and Safety

Finite element analysis: Importing into ANSYS software for stress analysis and optimizing weak areas (such as hollow-out edges and corners) to ensure UHPC form strength meets standards (flexural strength ≥30MPa). After analysis, Qinglong optimized the frame width of its highly perforated forms to 50mm, balancing aesthetics and safety. Production feasibility verification: Simulating mold making and grouting processes to avoid issues such as demolding difficulties and air bubble retention. Qinglong reserves a draft angle (≥3°) during modeling to reduce production risks. Installation simulation: Simulating on-site installation with BIM software to optimize lifting points and panel assembly sequences. In Qinglong's Shenzhen Pingshan High-tech Zone project, installation simulation shortened the construction period by 20%.

4. Mold Data Conversion and Output: Connecting to Production

Mold splitting design: Dividing the overall form into producible mold modules with module joint precision of ≤±0.5mm. Qinglong's mold splitting for complex forms follows a "whole-first, parts-second" principle, balancing production efficiency and precision. Data format conversion: Converting modeling data into CNC machining formats (such as STL and IGES) for direct connection with mold machining equipment. Qinglong's data conversion error is ≤±0.1mm, ensuring molds precisely replicate the form. Production file output: Generating a full set of documents including mold machining drawings, bills of materials, and production process parameters to guide factory production. Qinglong's output files include detailed tolerance requirements to ensure consistency in mass production.

5. Qinglong's Digital Modeling Advantages and Project Evidence

Technical team support: A professional digital design team of more than 20 members, each proficient in 3 or more modeling software programs, completing over 500 complex form models annually. Patented technology: Holding 5 patents related to parametric modeling, and participating in establishing the modeling standards of the "General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components." Project evidence: The Shanghai Astronomy Museum sculpture project took only 7 days to model, with shape fidelity of 99.5%; the 11,500㎡ double-curved panels for the Guangxi New Media Center achieved modeling errors of ≤±0.4mm, with all panels installed seamlessly.
