基于混合现实的两端全框支梁受力状态原位有限元仿真方法
By combining optical measurement and boundary condition inverse identification techniques with augmented reality technology, the problem of insufficient perception of support constraint characteristics in mixed reality simulation systems has been solved. This has enabled high-precision in-situ simulation and intuitive evaluation of beam-supported structures, ensuring the accuracy of simulation results and the reliability of structural safety assessment.

Abstract
本发明涉及电子数据数字处理技术领域，公开了基于混合现实的两端全框支梁受力状态原位有限元仿真方法。该方法通过混合现实设备获取支梁及支座的三维几何模型，并利用高帧率相机捕捉受激状态下的全场位移数据；构建以支座转动刚度为未知参数的有限元模型，通过迭代优化算法逆向辨识真实刚度值；将修正后的模型在设计荷载下求解，并将应力、应变及变形云图通过混合现实设备空间配准叠加至真实结构上。该系统包括三维感知、微变捕捉、边界辨识、模型更新与混合现实可视化5大模块。本发明实现了边界条件原位精确辨识、非接触无损检测及沉浸式可视化评估，显著提升结构安全分析的准确性与效率。
