摘要:

选矿厂设计过程涉及大量数据计算、图形绘制以及设计规范和设计经验的应用,计算机辅助设计的应用无疑能显著提高设计效率和质量。通过对选矿厂计算机辅助设计研究现状进行总结和分析,指出存在的问题和不足,即设计过程模块化、设计规范和经验处理不成熟、设备配置自主化和可视化程度低以及沉浸感缺乏等。计算机虚拟现实技术(VR)的出现,为解决这些问题和不足提供了新的技术途径,将VR技术应用于选矿厂设计中,可有效提升设计过程的自主化、可视化、沉浸感以及人机交互性与设计员的想象创造力,是未来选矿厂计算机辅助设计的重要发展方向。

Abstract:

The design of the mineral processing plant is a complicated and important work,which involves a lots of data calculation,graphic drawing and the application of the design standards and experience.The most traditional design process mainly relies on manual calculation and drawing,which usually takes a large amount of time and energy to complete.Moreover,it is difficult to find the problems in the design in time,and it is also troublesome to modify the data and graphics.With the development of computer technology,the development and application of computer aided design software can significantly improve the efficiency and quality of the operation in the process of design and drawing of the mineral processing plant.Through the research and development of the software of process and equipment selection calculation,two-dimensional and three-dimensional graphics drawing,the repetitive and regular calculation and drawing steps in the design process can be reduced,and all kinds of errors happened in the engineering drawing is reduced at the same time.In addition,the application of the expert system technology,solved the problem of design standards and experience in the design process of the mineral processing plant to a certain extent,which can make computer participate in the design process,rather than just acting as a design tool.But at present,there are still deficiencies in the computer-aided design of mineral processing plant,such as the fragmentation of design process,the immature treatment of design specifications and experience,the lack of autonomy,visualization and immersion of equipment layout and so on.With the continuous development of computer technology,the rise of modern virtual reality technology provides a new and optional technical way to solve the existing deficiencies in the computer-aided design of mineral processing plant.The virtual reality technology integrates multi-computer technologies such as multimedia,graphics,simulation and artificial intelligence,which can greatly improve the autonomy,visualization and immersion of the design process,as well as human-computer interaction and designers'imagination and creativity.It has been widely used in many fields and industries,and has achieved some effective results.In the field of the mineral processing plant design,the application of virtual reality technology is still in the preliminary exploration stage,but it has great research potential and research value,and it will be an important development direction of the computer-aided design of mineral processing plant in the future.

Key words: mineral processing plant design, computer aided design, virtual reality technology, mineral processing technology, equipment layout, three-dimension design
