【摘要】：制造業(yè)的日益繁榮促使三維軟件在機(jī)械設(shè)計(jì)中的使用越來越廣泛,很多企業(yè)開發(fā)了自己的零件庫。隨著計(jì)算機(jī)網(wǎng)絡(luò)技術(shù)的逐漸成熟,基于網(wǎng)絡(luò)的CAD/CAM技術(shù)將成為未來軟件發(fā)展的方向�；ヂ�(lián)網(wǎng)的發(fā)展使不同地域、不同行業(yè)之間的通訊與協(xié)作成為可能,網(wǎng)絡(luò)虛擬展示技術(shù)的應(yīng)用,使用戶從單純的二維瀏覽中解脫出來,通過在線對(duì)模型文件的縮放、移動(dòng)和旋轉(zhuǎn)等操作,用戶可以直觀的觀察產(chǎn)品結(jié)構(gòu)特征,獲取產(chǎn)品信息。本文在分析當(dāng)前零件模型庫的現(xiàn)狀與不足的基礎(chǔ)上,并結(jié)合互聯(lián)網(wǎng)的發(fā)展現(xiàn)狀,提出了一套基于網(wǎng)絡(luò)的機(jī)電類產(chǎn)品通用部件虛擬模型庫的設(shè)計(jì)思想,并進(jìn)行了初步嘗試。 利用三維造型軟件建立部件模型,為了增強(qiáng)真實(shí)感,在具有強(qiáng)大渲染功能的3Dmax軟件中進(jìn)行貼圖和渲染,再通過Cult 3D Exportor插件導(dǎo)入Cult 3D Designer編輯并進(jìn)行交互的設(shè)置,搭建Cult3D的Java代碼開發(fā)環(huán)境,構(gòu)建部件產(chǎn)品的在線交互展示模型。 系統(tǒng)以Windows XP作為平臺(tái),采用基于網(wǎng)絡(luò)的B/S(Browser/Server)模式,根據(jù)服務(wù)器端的腳本編程技術(shù)、ASP訪問數(shù)據(jù)庫的原理設(shè)定數(shù)據(jù)源,建立網(wǎng)頁與數(shù)據(jù)庫的鏈接。該模型庫系統(tǒng)分為三個(gè)層次結(jié)構(gòu):網(wǎng)絡(luò)數(shù)據(jù)庫層、邏輯層和應(yīng)用層,其中應(yīng)用層采用模塊化設(shè)計(jì),以適應(yīng)數(shù)據(jù)庫連接的模塊化。采用Visual studio軟件,借助C#、JavaScript腳本語言對(duì)系統(tǒng)的站點(diǎn)、Web頁和Web應(yīng)用程序進(jìn)行設(shè)計(jì)、編碼和開發(fā)。整個(gè)系統(tǒng)通過網(wǎng)絡(luò)環(huán)境集成產(chǎn)品搜索、交互瀏覽、模型下載、在線訂貨和管理維護(hù)等模塊。通過編寫JavaScript腳本語言,實(shí)現(xiàn)模型的拖動(dòng)下載,用戶可直接將模型從系統(tǒng)中拖動(dòng)到三維軟件的裝配環(huán)境中,設(shè)置裝配基準(zhǔn)和約束條件。 系統(tǒng)實(shí)現(xiàn)了在有限的帶寬下產(chǎn)品的在線交互瀏覽、模型的拖動(dòng)下載和產(chǎn)品在線訂購等功能,方便了設(shè)計(jì)師的使用,縮短了產(chǎn)品開發(fā)周期,也為部件供應(yīng)商提供了展示和銷售產(chǎn)品的服務(wù),降低了零部件的銷售成本。系統(tǒng)向個(gè)人用戶(主要針對(duì)機(jī)械設(shè)計(jì)師)免費(fèi)開放,部件商通過購買使用權(quán)對(duì)模型庫進(jìn)行資金支持,維持模型庫的運(yùn)營(yíng)。系統(tǒng)的投入使用,為用戶提供了一種新型網(wǎng)上CAD信息共享平臺(tái),具有廣泛的應(yīng)用前景。
[Abstract]:With the prosperity of manufacturing industry, 3D software is widely used in mechanical design, and many enterprises have developed their own parts library. With the maturity of computer network technology, CAD/CAM technology based on network will become the direction of software development in the future. The development of the Internet makes it possible to communicate and cooperate between different regions and different industries. The application of network virtual display technology frees users from simple two-dimensional browsing and scales the model files online. Moving and rotating operations, users can intuitively observe the characteristics of the product structure, obtain product information. Based on the analysis of the current situation and deficiency of the part model base and the development of the Internet, this paper puts forward a set of design ideas of the virtual model base of the general components of electromechanical products based on the network, and makes a preliminary attempt. Using 3D modeling software to build component model, in order to enhance the reality, map and render in 3Dmax software with powerful rendering function, then import Cult 3D Designer edit and set up interactive through Cult 3D Exportor plug-in. The Java code development environment of Cult3D is built, and the online interactive display model of component products is constructed. The system takes Windows XP as the platform, adopts the B / S (Browser/Server) mode based on the network, sets up the data source according to the principle of the script programming technology in the server side to access the database, and establishes the link between the web page and the database. The model base system is divided into three hierarchies: the network database layer, the logic layer and the application layer. The application layer is designed by modularization to adapt to the modularization of database connection. The Visual studio software is used to design, encode and develop the web page and Web application program of the system. The whole system integrates product search, interactive browsing, model download, online ordering and management and maintenance through the network environment. By writing the JavaScript script language, the model can be dragged and downloaded. The user can directly drag the model from the system to the assembly environment of 3D software, and set up the assembly benchmark and constraint conditions. The system realizes the functions of online interactive browsing of products under limited bandwidth, dragging and downloading of models and online ordering of products, which facilitates the use of designers and shortens the product development cycle. It also provides parts suppliers with the services to display and sell products, reducing the cost of parts sales. The system is open to individual users (mainly for mechanical designers) free of charge. Component vendors support the model base by purchasing the right of use and maintain the operation of the model base. The application of the system provides users with a new online CAD information sharing platform, which has a wide application prospect.
