基于VR的塑料虚拟注射成型系统的研究与实现

Research and Development of VR-Based Virtual Plastic Injection Molding System

虚拟现实,作为一门新型技术,已成功地应用于工程、设计和制造业领域。本文提出并实现一种基于虚拟现实技术(VR)的塑料注射成型的可视化交互式仿真系统。创新的采用Delaunay三角剖分技术进行成型设备的三维建模,同时提出了模拟注射成型过程运动仿真的方法,结合基于三维模型的注射成型FEA技术,创建注射成型仿真系统。整个系统可在塑料新产品设计的早期阶段及时的发现产品设计和工艺过程中可能出现的错误和缺陷,进行产品设计和生产工艺的优化,保证产品质量,节省开发新产品的时间和费用。

Virtual reality （VR）, as a new technology, is integrated with software systems for engineering, design, and manufacturing. Visual interactive simulation system based on VR for plastic injection molding was proposed and completed. Key techniques （FEA, Delaunay Triangulation, movement simulating approach） of the system were described in detail. The overall system is a new powerful approach for highly relevant industrial application of VPIM which focuses on the construction and assessment of alternate manufacturing sequences and mould design in an early design stage. Improvement of their design and manufacturing process will lead to savings in better design and reduce development time and cost.
