【摘要】：虛擬現(xiàn)實技術(Virtual Reality)是由計算機與電子相結合產生的新技術,它綜合應用傳感器、人工智能、立體顯示等多項技術模擬出具有真實感與沉浸感的人工虛擬環(huán)境。虛擬現(xiàn)實技術產生的是一種多感知虛擬環(huán)境,除了常見的視覺感知以外,還包括聽覺、嗅覺和觸覺等其他方面的感知。借助視覺顯示設備與人機交互設備,虛擬現(xiàn)實系統(tǒng)可以使使用者實時感知與操作虛擬場景中的對象,得到身臨其境感受。虛擬現(xiàn)實技術由于強大的人機交互能力,現(xiàn)已廣泛應用于工業(yè)設計與制造、軍事、航天、醫(yī)學康復、影視、考古研究、教育等多個領域。隨著計算機技術的不斷發(fā)展,擁有“低成本、高性能”特點的虛擬現(xiàn)實技術展現(xiàn)出越來越大的發(fā)展前景。立體顯示系統(tǒng)是虛擬現(xiàn)實系統(tǒng)中的重要組成,是進行交互性操作的基礎。全斷面隧道掘進機(Full Face Rock Tunnel Boring Machine)是集液壓、機械、電子、電氣、控制等多項技術于一體,應用于隧道施工的高度機械化與自動化的大型工程設備。掘進機具有綜合效益好、自動化程度高、不受外界氣候影響等諸多優(yōu)點,是現(xiàn)在隧道施工使用最普遍、應用前景最廣闊的機械設備。本文研究的敞開式硬巖隧道掘進機適用于硬巖地層的開挖,破巖機理主要是在刀盤與滾刀的綜合作用下,巖石產生溝槽的深度不斷加深進而發(fā)生斷裂,最后從巖石表面剝落下來完成破巖。未來的幾十年內,我國城市地鐵工程、山路交通、越江穿海隧道等各項建設需要各種不同直徑、不同類型的隧道需要開挖,掘進機市場需求巨大并會在未來一段時間持續(xù)增長,因此加大對TBM的理論研究和產品開發(fā)力度將是非常必要的。由于掘進機特殊的施工布置環(huán)境使得我們很難進行觀察研究,所以運用虛擬現(xiàn)實技術對施工場景進行施工模擬是一個很好的研究途徑,并且對于其它大型工程機械設備也具有很好的工程適用性。本文主要研究內容是敞開式硬巖隧道掘進機視景仿真系統(tǒng)開發(fā)。課題以德國維爾特公司生產的803E敞開式硬巖隧道掘進機作為研究對象,基于MultiGen Creator完成敞開式硬巖隧道掘進機施工場景的框架構建,并對材質、紋理映射、布告板技術、LOD技術、實例化技術做進行了深入的研究。綜合使用以上技術創(chuàng)建了逼真的施工場景,很好地滿足了虛擬視景仿真的需要。采用自頂向下的裝配設計方法,在Pro/E軟件中構建敞開式硬巖隧道掘進機的三維模型,按照運動關系對各個部件進行裝配調整,并通過轉換得到可以在虛擬現(xiàn)實軟件中處理的數(shù)據(jù)格式,完成掘進機模型在虛擬現(xiàn)實環(huán)境下的裝配。對掘進機施工過程的運動部件設置了DOF節(jié)點,并對掘進機數(shù)據(jù)模型進行了優(yōu)化,生產了OpenFlight數(shù)據(jù)格式�；�于MultiGen Vega軟件的LynX界面,對掘進機模型與虛擬場景進行了配置,生產了程序定義文件。采用Visual C++6.0作為編譯環(huán)境,在MFC框架下開發(fā)了Vega應用程序,完成了掘進機復雜施工過程的模擬,并具有很好的交互性。通過被動立體投影系統(tǒng),得到了具有沉浸感的掘進機施工立體顯示效果。
[Abstract]:Virtual reality technology (Virtual Reality) is a combination of computer and electronic technology produced, its comprehensive application of sensor, artificial intelligence, etc. stereo display technology to simulate virtual environment with artificial sense of reality and immersion. Virtual reality technology is a multisensory virtual environment, in addition to the visual perception of common also, including auditory, olfactory and tactile perception. With the help of other aspects of the visual display devices and human-computer interaction, virtual reality system can make the real-time operation and object perception in virtual scene, be personally on the scene feel. The virtual reality technology for interactive ability strong, has been widely used in design and manufacturing, industrial and military. Aerospace, medical rehabilitation, television, archaeological research, many fields of education. With the development of computer technology, with low cost, high performance characteristics The virtual reality technology prospects for development more and more. The stereoscopic display system is an important component in virtual reality system, is the basis for interactive operation. TBM (Full Face Rock Tunnel Boring Machine) is a set of hydraulic, mechanical, electronic, electrical, control and other technology, large highly mechanized engineering equipment used in tunnel construction and automation. The roadheader has good comprehensive benefits, high degree of automation, many advantages from the outside world weather, is now the most commonly used construction machinery and equipment, the most promising excavation. Open hard rock tunnel boring machine in this paper is suitable for hard rock strata, rock breaking mechanism is mainly on the comprehensive effect of cutter and hob, rock groove depth deepening and fracture, finally peeled off from the surface of the rock breaking down Rock. The next few decades, the city subway project, China's road traffic, the construction of river crossing tunnel Chuanhai with different diameter, different types of tunnel boring machine to excavation, huge market demand and continued growth in the next period of time, thus increase the TBM theoretical research and product development efforts will be necessary. As the construction layout of TBM special environment makes it difficult to study, so the construction simulation of the construction scene is a good way to research the use of virtual reality technology, and also has a good engineering applicability for other large engineering machinery and equipment. The main content of this paper is open hard rock tunnel boring machine visual simulation system development project. Produced by German Wirth 803E open hard rock tunnel boring machine as the research object, based on the MultiGen Creator. A framework of open type hard rock tunnel boring machine construction scene, and the material, texture mapping, bulletin board technology, LOD technology, instantiation technology is studied. Using the above technology comprehensive construction to create a realistic scene, very good to meet the needs of virtual scene simulation. Using assembly design method the top-down construction of three-dimensional model of open type hard rock tunnel boring machine in the Pro/E software, the assembly adjustment on various components according to motion relations, and can handle in virtual reality software through the data format conversion, boring machine assembly model in virtual reality environment. The moving parts of TBM construction process set the DOF node, and the tunneling machine data model was optimized, and production of the OpenFlight data format. MultiGen Vega software based on LynX interface, the tunneling machine model and virtual field The scene is configured, the production procedure definition file. Using Visual C++6.0 as the compiling environment, Vega application development under the framework of MFC, completed the simulation of construction process of complex boring machine, and has good interactivity. The passive stereo projection system, obtained with TBM immersive stereoscopic display effect.
