摘要
基于物理的模拟对于设计自主建筑设备至关重要,但准备模型非常耗时,需要整合机械和几何数据。目前模块化机器人的自动建模方法不足以用于建筑设备。本文通过将机械数据集成到三维计算机辅助设计(CAD)模型中,探索建模过程的自动化。本文开发了一个模板库,其中包含设备专用的层次结构和关节模板。在模型生成过程中,根据设备类型选择合适的模板。使用大型语言模型(LLM)从技术规范中提取未指定的关节模板数据。然后将 3D CAD 模型转换为通用场景描述(USD)模型。用户可以调整通用场景描述模型中的零件名称和层次结构,使其与层次结构模板相一致,并自动整合接头数据,从而生成一个可用于仿真的模型。与手动方法相比,这种方法在保持精度的同时,将建模时间缩短了 87% 以上。
Automated physics-based modeling of construction equipment through data fusion
Physics-based simulations are essential for designing autonomous construction equipment, but preparing models is time-consuming, requiring the integration of mechanical and geometric data. Current automatic modeling methods for modular robots are inadequate for construction equipment. This paper explores automating the modeling process by integrating mechanical data into 3D computer-aided design (CAD) models. A template library is developed with hierarchy and joint templates specific for equipment. During model generation, appropriate templates are selected based on the equipment type. Unspecified joint template data is extracted from technical specifications using a large language model (LLM). The 3D CAD model is then converted into a Universal Scene Description (USD) model. Users can adjust the part names and hierarchy within the USD model to align with the hierarchy template, and joint data is automatically integrated, resulting in a simulation-ready model. This method reduces modeling time by over 87 % compared to manual methods, while maintaining accuracy.
