【摘要】：隨著虛擬現(xiàn)實技術(shù)的發(fā)展,虛擬仿真教學(xué)實驗系統(tǒng)在專業(yè)知識教學(xué)和設(shè)備操作培訓(xùn)中占據(jù)著越來越重要的作用,它以不可或缺的眾多優(yōu)勢,彌補了傳統(tǒng)高校教學(xué)和企業(yè)培訓(xùn)過程中存在的諸多問題,滿足了日益增長的教學(xué)質(zhì)量和企業(yè)人員培訓(xùn)的要求。沖床在國民生產(chǎn)中作為一種最常見的機床,用途十分廣泛,而且沖床的操作培訓(xùn)安全要求較高,現(xiàn)階段的教育資源無法滿足學(xué)生的實踐要求,同時,目前市面上的虛擬沖床教學(xué)仿真系統(tǒng)普遍存在功能開發(fā)不到位,缺少CAE分析功能和完整沖壓工藝過程演示等缺點。為了解決上述問題,在現(xiàn)有的研究成果基礎(chǔ)上,本文結(jié)合UG,3ds Max和Unity3D開發(fā)引擎,基于MVC設(shè)計模式的總體框架設(shè)計理論以及功能模塊化的設(shè)計思想,設(shè)計開發(fā)了一款基于虛擬現(xiàn)實技術(shù)的虛擬沖床仿真系統(tǒng),通過逼真的虛擬場景,功能豐富的交互性操作,全方位的案例教學(xué)以及強大的CAE板料分析功能來滿足學(xué)校和企業(yè)的培訓(xùn)需求,提高培訓(xùn)人員沖床的實踐操作能力,達到最好的教學(xué)成果。本文設(shè)計的虛擬沖床仿真系統(tǒng)為滿足學(xué)生多種CAE分析需求,分別開發(fā)了兩種不同的板料沖壓成形功能,其中板料沖壓成形精確分析功能是基于華中科技大學(xué)塑性成形模擬及模具技術(shù)國家重點實驗室柳玉起教授團隊設(shè)計的FASTAMP板料沖壓成形分析軟件的算法,加以優(yōu)化并應(yīng)用開發(fā)的,而另外一種板料沖壓成形快速分析功能是基于一種自主設(shè)計,以空間網(wǎng)格布爾運算為前提的可適性快速成形算法而開發(fā)的。兩種功能的結(jié)合提供了學(xué)生豐富的操作體驗。此外,為了滿足板料沖壓成形分析算法的通用性,本文還設(shè)計了一種任意平面域多邊形三角剖分算法。此算法考慮了平面多邊形的多種特殊情況,在產(chǎn)生最優(yōu)三角網(wǎng)格的前提下,完美的適用兩種板料沖壓成形算法,且穩(wěn)定性高,可適性強,具有非常好的實時性和可靠性。
[Abstract]:With the development of virtual reality technology, virtual simulation teaching experiment system plays a more and more important role in professional knowledge teaching and equipment operation training. It makes up for many problems existing in the process of teaching and enterprise training in traditional colleges and universities, and meets the requirements of the increasing teaching quality and the training of enterprise personnel. As one of the most common machine tools in national production, punching machines are widely used, and the safety requirements for operation training of punching machines are high. At this stage, the educational resources cannot meet the practical requirements of students. At the same time, At present, the virtual punch teaching simulation system on the market has some shortcomings, such as the lack of function development, the lack of CAE analysis function and the complete stamping process demonstration, etc. In order to solve the above problems, based on the existing research results, this paper combines UG,3ds Max and Unity3D development engine, the overall framework design theory based on MVC design pattern and the design idea of function modularization. A virtual punching machine simulation system based on virtual reality technology is designed and developed. The omni-directional case teaching and the powerful function of CAE sheet metal analysis can meet the training needs of schools and enterprises, improve the practical operation ability of the trainers' punching machine, and achieve the best teaching results. The virtual punching machine simulation system designed in this paper has developed two kinds of different sheet metal stamping forming functions to meet the needs of various CAE analysis of students. The precise analysis function of sheet metal forming is based on the algorithm of FASTAMP sheet metal forming analysis software designed by Professor Liu Yuqi, State key Laboratory of plastic forming Simulation and Die Technology, Huazhong University of Science and Technology. The other rapid analysis function of sheet metal forming is based on an adaptive rapid prototyping algorithm based on spatial grid Boolean operation. The combination of the two functions provides students with a rich experience of operation. In addition, in order to satisfy the generality of sheet metal forming analysis algorithm, an arbitrary plane polygon triangulation algorithm is designed in this paper. This algorithm takes into account many special cases of planar polygon. On the premise of generating optimal triangular mesh, this algorithm is perfect for two kinds of sheet metal stamping forming algorithms, and has high stability, strong adaptability, and very good real-time and reliability.
