摘要: 针对复杂装备运行过程中结构应力状态难以实时获取和直观分析的问题，本文设计并实现了一种基于Unity的应力场实时预测仿真系统。系统以三维仿真场景为基础，将仿真对象的运动状态与发电机重力、起升高度和装置侧向力等工况参数进行统一组织，并以有限元计算数据为基础建立应力场代理模型，实现不同工况下结构应力场的快速预测。在此基础上，通过数据传递与动态更新机制，将预测结果映射至三维模型表面，并利用Shader实现应力云图的动态可视化，从而建立工况参数、应力预测与三维显示之间的关联。结果表明，该系统能够根据当前工况快速获得对应的应力场分布，并实现预测结果与仿真状态的同步更新，为复杂装备运行过程中的应力状态实时预测与可视化分析提供了一种可行的实现方法。

Abstract: To address the difficulty of obtaining and intuitively analyzing structural stress states during the operation of complex equipment, a Unity-based simulation system for real-time stress field prediction is designed and implemented. Based on a three-dimensional simulation environment, the system organizes the motion state of the simulated object together with operating parameters including generator gravity, lifting height, and lateral force. A stress field surrogate model is established based on finite element simulation data to achieve rapid prediction of structural stress fields under different operating conditions. Furthermore, through data transmission and dynamic updating mechanisms, the predicted results are mapped onto the surface of the three-dimensional model, and a Shader-based visualization method is employed to generate dynamic stress cloud maps. This establishes an integrated process connecting operating conditions, stress prediction, and three-dimensional visualization. The results show that the proposed system can rapidly obtain the corresponding stress field distribution according to the current operating conditions and synchronously update the prediction results with the simulation state, providing a feasible approach for real-time stress prediction and visual analysis during the operation of complex equipment.
