(6) Virtual prototype and product performance evaluation
Design, remanufacturing and other repeated trial production processes, many unreasonable design and wrong design can only be found in the manufacturing, assembly process, even when the prototype test. The quality and performance of the product can only be judged by trial operation after the product is produced. At this time, most of the problems cannot be changed. Modifying the design means partial or complete scrapping and re-production. Therefore, it is often necessary to carry out multiple trial productions to meet the requirements, and the trial production cycle is long and the cost is high. With virtual manufacturing technology, the design scheme and structure can be simulated at the design stage to solve most problems and improve the power of one trial production. With virtual reality technology, work performance checks can be performed easily and intuitively. For example, John Deere of the United States used this technology to model and simulate the three technical solutions of the new product backhoe loader. The results negated two of them and saved a lot of development funds. Figure 1 shows the virtual loader model made with dVISE.
(7) Product advertising and roaming
Product advertisements made with virtual reality or 3D animation technology have realistic effects, showing not only the shape of the product, but also the internal structure of the product, the assembly and maintenance process, the method of use, the working process, the work performance, etc., especially the use of the network. The product introduction, the advertising effect is very good. For example, the product introduction and user instructions of a copier on the internet network can be operated on the Internet: copying, opening the side panel of the copier to display the internal structure, replacing the ink cartridge, cleaning the drum, removing the jammed paper, closing the side panel, etc. Vivid and intuitive.
Roaming technology enables people to roam between cities, factories, workshops, machines, and even drawings and parts, providing intuitive and convenient access to information.
3. Product manufacturing technology in virtual reality environment
Product design, manufacturing, and evaluation in a virtual reality environment begins with stereo modeling of the product, and then places the model in a virtual environment for control and analysis. As virtual reality technology is developing, virtual reality environment software is relatively mature, such as WTK, dVISE, VRT, etc., and the software functions for simulation and control of mechanical design and manufacturing are relatively scattered, and the connection between the two is not yet Maturity is a hot spot for research and development. Such as mechanical motion simulation, sheet metal forming analysis and simulation, part processing and assembly simulation. At present, feature-based 3D modeling technology is gradually becoming practical and starting to promote applications, providing us with a solid foundation. However, these modeling software does not support virtual reality environments and must be converted and processed.
Based on the unit's product parking garage, we have established a parametric design system in the virtual reality environment, including: garage layout design, garage type selection, garage design and garage work demonstration system, and initially realized parametric virtual design. The system is programmed with VC and OpenGL, and the complex model is modeled using AUTOCAD and 3DS MAX. In this virtual design software, parametric modeling can be used to visualize the layout, design, analysis and motion simulation of the garage.
