基于虚拟环境的驾驭式动态设计

VIRTUAL REALITY BASED STRUCTURAL DYNAMIC DESIGN STEERING TECHNIQUE

提出了基于虚拟环境的驾驭式动态设计方法。该方法使得结构动态设计过程的各个阶段都成为一个包括设计人员和虚拟环境在内的回路,既可以将设计过程及时全面地展示给设计人员,又能够让设计人员方便地对设计过程进行驾驭,充分发挥其经验和创造力。在探讨了该方法的基本思想之后,着重研究了相应的关键技术和系统实现。在此基础上,用一个浸水旋转壳的动态设计过程证明了该方法具有可视化程度高、便于驾驭等优点。

A virtual environment based dynamic design steer- ing method is proposed. With virtual reality and computation steering techniques utilized, the structural dynamic design pro- cess becomes a close-loop that made up of a classical dynamics design sub-system, a virtual environment and designers. This displays the dynamic design process to designers in good time, and helps designers to track on the dynamic design process and to steer it expediently. After discussing the basic theory,key techniques and system implementation of this method are stud- ied in detal. An example of dynamic design of a submerged rotating-shell is given to demonstrate that structural dynamic design process that can be visualized and steered expediently by means of the presented method.
