【摘要】：網(wǎng)絡(luò)虛擬實(shí)驗(yàn)對(duì)于高校實(shí)驗(yàn)教學(xué)具有重大意義和應(yīng)用價(jià)值。當(dāng)前計(jì)算機(jī)技術(shù)、虛擬現(xiàn)實(shí)技術(shù)和網(wǎng)絡(luò)技術(shù)的快速發(fā)展,為建立逼真的三維實(shí)驗(yàn)設(shè)備及環(huán)境、實(shí)現(xiàn)復(fù)雜的實(shí)驗(yàn)交互功能、遠(yuǎn)程訪問實(shí)驗(yàn)教學(xué)資源提供了必要條件。本文以機(jī)械學(xué)科的課程實(shí)驗(yàn)為對(duì)象,研究了虛擬實(shí)驗(yàn)的實(shí)現(xiàn)方法,構(gòu)建了虛擬實(shí)驗(yàn)系統(tǒng)。該方法采用VRML(虛擬現(xiàn)實(shí)建模語(yǔ)言)描述機(jī)械學(xué)科虛擬實(shí)驗(yàn)的設(shè)備和場(chǎng)景,利用VC程序?qū)崿F(xiàn)用戶與虛擬實(shí)驗(yàn)設(shè)備及場(chǎng)景的交互和控制。主要研究成果包括: 第一、提出了機(jī)械學(xué)科網(wǎng)絡(luò)虛擬實(shí)驗(yàn)的系統(tǒng)框架。該系統(tǒng)利用VC開發(fā)ActiveX實(shí)驗(yàn)控件,將VRML描述的實(shí)驗(yàn)場(chǎng)景嵌入其中,通過VC與VRML的數(shù)據(jù)通信,實(shí)現(xiàn)虛擬實(shí)驗(yàn)功能。 第二、針對(duì)機(jī)械學(xué)科虛擬實(shí)驗(yàn)對(duì)機(jī)構(gòu)建模和設(shè)備仿真的需求,對(duì)VRML的造型功能進(jìn)行了擴(kuò)展,提出了構(gòu)建機(jī)械學(xué)科典型零件和機(jī)構(gòu)的建模方法;利用VRML中的坐標(biāo)系嵌套、多層傳感器結(jié)構(gòu)和腳本路由機(jī)制,建立起了復(fù)雜機(jī)構(gòu)設(shè)備的運(yùn)動(dòng)仿真模型。 第三、針對(duì)VRML控制功能的不足,采用VC程序?qū)RML場(chǎng)景進(jìn)行輔助控制,提高了虛擬實(shí)驗(yàn)場(chǎng)景的交互性和可控性。編程實(shí)現(xiàn)了實(shí)驗(yàn)數(shù)據(jù)的生成和管理,滿足了實(shí)驗(yàn)數(shù)據(jù)的擬真性;用軟件實(shí)現(xiàn)了虛擬設(shè)備的核心功能,完善了虛擬實(shí)驗(yàn)的功能系統(tǒng)。 最后,選取“互換性與技術(shù)測(cè)量”的課程實(shí)驗(yàn)為對(duì)象,利用本文提出的方法構(gòu)建了該課程的網(wǎng)絡(luò)虛擬實(shí)驗(yàn),實(shí)現(xiàn)了課程實(shí)驗(yàn)的功能。 本文采用VC和VRML相結(jié)合的方法構(gòu)建機(jī)械學(xué)科網(wǎng)絡(luò)虛擬實(shí)驗(yàn),可以很好地還原實(shí)際實(shí)驗(yàn)場(chǎng)景,交互性強(qiáng),能夠比較全面地演繹實(shí)際實(shí)驗(yàn)的功能,在高校實(shí)驗(yàn)教學(xué)資源共享和遠(yuǎn)程教育方面有很好的應(yīng)用前景。
[Abstract]:Network virtual experiment has great significance and application value for experimental teaching in colleges and universities.The rapid development of computer technology, virtual reality technology and network technology provides the necessary conditions for the establishment of lifelike three-dimensional experimental equipment and environment, the realization of complex experimental interactive functions, and remote access to experimental teaching resources.In this paper, the realization method of virtual experiment is studied, and the virtual experiment system is constructed.In this method, VRML (Virtual reality Modeling language) is used to describe the equipment and scene of mechanical virtual experiment, and VC program is used to realize the interaction and control between user and virtual experiment equipment and scene.The main findings include:First, the system framework of network virtual experiment of mechanical discipline is proposed.The system uses VC to develop ActiveX experimental control and embed the experimental scene described by VRML into it. The virtual experiment function is realized through the data communication between VC and VRML.Secondly, aiming at the requirement of mechanism modeling and equipment simulation in the virtual experiment of mechanical discipline, the modeling function of VRML is extended, and the modeling method of typical parts and mechanism of mechanical discipline is put forward, and the nesting of coordinate system in VRML is used.The multilayer sensor structure and script routing mechanism are used to establish the motion simulation model of complex mechanism.Thirdly, aiming at the deficiency of VRML control function, VC program is used to control the VRML scene, which improves the interaction and controllability of the virtual experimental scene.Programming realizes the generation and management of experimental data, satisfies the simulation of experimental data, realizes the core function of virtual equipment with software, and perfects the functional system of virtual experiment.Finally, the course experiment of "interchangeability and technical measurement" is selected as the object, and the network virtual experiment of the course is constructed by using the method proposed in this paper, and the function of the course experiment is realized.In this paper, the method of combining VC and VRML is used to construct the network virtual experiment of mechanical discipline, which can well restore the actual experimental scene, have strong interactivity, and can fully deduce the function of the actual experiment.It has a good application prospect in the sharing of experimental teaching resources and distance education in colleges and universities.
