基于WebGL和有限元的码头三维设计与计算仿真

在复杂的码头工程中，三维设计与有限元计算仿真不仅能够解决Autocad图纸表现力不足的问题，还能提高设计 效率，为结构分析和优化设计提供有力参考。针对码头平面设计难以与有限元计算衔接、三维有限元模型难以用于交流的 问题，将有限元与WebGL技术结合起来，开发出一套3D设计仿真一体化程序。该程序依托Autocad、Adina平台，从二维图 纸出发，能够半自动化地生成有限元计算文件，该文件可以直接提交运算，得到应力、温度等各项指标。计算结果经过进 一步处理能够在网络平台展示计算结果、实现界面交互。该套技术方案实现了3D设计、计算、展示的统一，成功地应用于 工程实例，取得了良好的效果。

3D design and simulation of wharf based on WebGL and FEM

In complicated wharf engineering, 3D-based design and FEM not only enhance performance of 2D drawing, and improve efficiency, but also offer strong reference to structure analysis and optimization. In order to better connect autoCAD drawing to FEM calculation and enable FEM file to communicate on the internet, FEM is combined with WebGL and a set of programmes for 3D design and analysis is developed. The programmes are run on Autocad and Adina platform, and start from 2D drawing, build FEM files semi-automatically, and the stress and temperature field are derived. The postfile is further processed so that we can display contour plots and execute interactive operation on internet. The whole set of technical solution integrates design, calculation and display. It is tested and verified on a project with satisfactory results.
