Development On The Virtual Laboratory Software System Of Materials Processing

Due to quality education policy and requirement of creative talents, it is imperative for universities to strengthen experimental teaching. And virtual reality technique brought new chance for it. With this technique experimental skill teaching efficient and process were improved. Combining techniques of virtual reality with multimedia, this paper researched virtual laboratory software system of materials processing engineering on basis of existing software and hardware. And this system provided a opening surrounding of person-computer alternation, friendly interface.Firstly, Virtual laboratory software system of material processing was established based on Visual Basic algorithms in this paper, which consists of material forming and control, mould design and manufacture, and welding virtual labs. So that the students can choose different labs and parameters in order to do some simple experiments as character of nature sand, mould assemble and numerical simulation of solidifying process.On Windows2000 software, this article established a virtual database system including data files, figures and video files of material processing virtual lab and built the relation of tables. At the same time, with software of Windows OLE DB database connection was set up. Using ADO of Visual Basic 6.0 to connect the data, the database mainly saved experimental equipments, apparatus, tools and results and established databases of digital figures, words and multimedia flashes.Based on CAD software such as UG and Solidworks and HZCAE system, experimental data design was researched, which includes three-dimension solid model and some figures of temperature field, flowing field and simulation filling in shape theory and mould dismount-installation experiments.Ground on the previous research, with technique of ASP this paper invented web part of the system that made students land the web, explore and experimentize, put in experimental report and communicate with the teacher on line.The research coordinates with the policy of building digital campus made out by the university to digitize from environment, resource to action.
