【正文】 echnical requirement of the user, the user training time from the past few weeks shorter for a few hours. Figure 1 is based on the central layer model and surface model based on 3D solid / flow analysis simulation parison chart.Finite element, finite difference, the control volume methodsInjection molding products are thin products, products in the thickness direction of size is much smaller than the other two dimensions, temperature and other physical quantities in the thickness direction of the change is very large, if the use of a simple finite element and finite difference method will cause analysis time is too long, can not meet the actual needs of mold design and manufacturing. We in the flow plane by using finite element method, the thickness direction by using finite difference method, were established and plane flow and thickness directions corresponding to the size of the grid and coupling, while the accuracy is guaranteed under the premise of the calculation speed to meet the need of engineering application, and using the control volume method is solved. The moving boundary problem in. For internal and external correspondence surface differences between products, can be divided into two parts the volume, and respectively formed the control equation, the junction of interpolation to ensure that the two part harmony contrast.Numerical analysis and artificial intelligence technologyOptimization of injection molding process parameters has been overwhelming majority of mold design staff concerns, the traditional CAE software while in puter simulation of a designated under the conditions of the injection molding conditions, but is unable to automatically optimize the technical parameters. Using CAE software personnel must be set to different process conditions were multiple CAE analysis, bined with practical experience in the program were pared between, can get satisfactory process scheme. At the same time, the parts after the CAE analysis, the system will generate a large amount of information about the project ( product, process, analyzes the results ), which often results in a variety of data form, requiring the user to have the analysis and understanding of the results of CAE analysis ability, so the traditional CAE software is a kind of passive putational tools, can provide users with intuitionistic, effective engineering conclusion, to software users demand is too high, the influence of CAE system in the larger scope of application and popularization. In view of the above, HSCAE3D software in the original CAE system based on accurate calculation function, the knowledge engineering technology is introduced the system development, the use of artificial intelligence is the ability of thinking and reasoning, instead of the user to plete a large number of information analysis and processing work, directly provide guiding significance for the process of conclusions and remendations, effectively solve the CAE of the plexity of the system and the requirements of the users of the contradiction between, shortening of the CAE system and the distance between the user, the simulation software by traditional passive putational tools to active optimization system. HSCAE3D system artificial intelligence technology will be applied to the initial design, the results of the analysis of CAE interpretation and evaluation, improvement and optimization analysis of3 aspects.附錄：科技英文中文翻譯注塑模具設(shè)計(jì)的技術(shù)1．用三維實(shí)體模型取代中心層模型　　傳統(tǒng)的注塑成形仿真軟件基于制品的中心層模型。用戶首先要將薄壁塑料制品抽象成近似的平面和曲面，這些面被稱為中心層。在這些中心層上生成二維平面三角網(wǎng)格，利用這些二維平面三角網(wǎng)格進(jìn)行有限元計(jì)算，并將最終的分析結(jié)果在中面上顯示。而注塑產(chǎn)品模型多采用三維實(shí)體模型，由于兩者模型的不一致，二次建模不可避免。但由于注塑產(chǎn)品的形狀復(fù)雜多樣、千變?nèi)f化，從三維實(shí)體中抽象出中心層面是一件十分困難的工作，提取過(guò)程非常繁瑣費(fèi)時(shí)，因此設(shè)計(jì)人員對(duì)仿真軟件有畏難情緒，這已成為注塑成形仿真軟件推廣應(yīng)用的瓶頸。　　HSCAE　3D主要是接受三維實(shí)體/表面模型的STL文件格式?，F(xiàn)在主流的CAD/CAM系統(tǒng)，如UG、Pro/ENGINEER、 CATIA和SolidWorks等，均可輸出質(zhì)量較高的STL格式文件。這就是說(shuō)，用戶可借助任何商品化的CAD/CAE系統(tǒng)生成所需制品的三維幾何模型的STL格式文件，HSCAE　3D可以自動(dòng)將該STL文件轉(zhuǎn)化為有限元網(wǎng)格模型，通過(guò)表面配對(duì)和引入新的邊界條件保證對(duì)應(yīng)表面的協(xié)調(diào)流動(dòng)，實(shí)現(xiàn)基于三維實(shí)體模型的分析，并顯示三維分析結(jié)果，免去了中心層模擬技術(shù)中先抽象出中心層，再生成網(wǎng)格這一復(fù)雜步驟，突破了仿真系統(tǒng)推廣應(yīng)用的瓶頸，大大減輕了用戶建模的負(fù)擔(dān)，降低了對(duì)用戶的技術(shù)要求，對(duì)用戶的培訓(xùn)時(shí)間也由過(guò)去的數(shù)周縮短為幾小時(shí)。圖1為基于中心層模型和基于三維實(shí)體/表面模型流動(dòng)分析模擬情況對(duì)比圖?！　?．有限元、有限差分、控制體積方法的綜合運(yùn)用　　注塑制品都是薄壁制品，制品厚度方向的尺寸遠(yuǎn)小于其他兩個(gè)方向的尺寸，溫度等物理量在厚度方向的變化又非常大，若采用單純的有限元或有限差分方法勢(shì)必造成分析時(shí)間過(guò)長(zhǎng)，無(wú)法滿足模具設(shè)計(jì)與制造的實(shí)際需要。我們?cè)诹鲃?dòng)平面采用有限元法，厚度方向采用有限差分法，分別建立與流動(dòng)平面和厚度方向尺寸相適應(yīng)的網(wǎng)格并進(jìn)行耦合求解，在保證計(jì)算精度的前提下使得計(jì)算速度滿足工程的需要，并采用控制體積法解決了成形中的移動(dòng)邊界問(wèn)題。對(duì)于內(nèi)外對(duì)應(yīng)表面存在差異的制品，可劃分為兩部分體積，并各自形成控制方程，通過(guò)在交接處進(jìn)行插值對(duì)比保證這兩部分的協(xié)調(diào)。3．?dāng)?shù)值計(jì)算與人工智能技術(shù)的結(jié)合　　優(yōu)選注塑成形工藝參數(shù)一直是廣大模具設(shè)計(jì)人員關(guān)注的問(wèn)題，傳統(tǒng)的CAE軟件雖然可以在計(jì)算機(jī)上仿真出指定工藝條件下的注塑成形情況，但無(wú)法自動(dòng)對(duì)工藝參數(shù)進(jìn)行優(yōu)化。CAE軟件使用人員必須設(shè)置不同的工藝條件進(jìn)行多次CAE分析，并結(jié)合實(shí)際經(jīng)驗(yàn)在各方案之間進(jìn)行比較，才能得出較滿意的工藝方案。同時(shí)，在對(duì)零件進(jìn)行CAE分析后，系統(tǒng)會(huì)產(chǎn)生有關(guān)該方案的大量信息(制品、工藝條件、分析結(jié)果等)，其中分析結(jié)果往往以各種數(shù)據(jù)場(chǎng)的形式出現(xiàn)，要求用戶必須具備分析和理解CAE分析結(jié)果的能力，所以傳統(tǒng)的CAE軟件是一種被動(dòng)式的計(jì)算工具，無(wú)法提供給用戶直觀、有效的工程化結(jié)論，對(duì)軟件使用者的要求過(guò)高，影響了CAE系統(tǒng)在更大范圍內(nèi)的應(yīng)用和普及。針對(duì)以上不足，HSCAE　3D軟件在原有CAE系統(tǒng)準(zhǔn)確的計(jì)算功能基礎(chǔ)上，把知識(shí)工程技術(shù)引入系統(tǒng)的開(kāi)發(fā)中，利用人工智能所具有的思維和推理能力，代替用戶完成大量信息的分析和處理工作，直接提供具有指導(dǎo)意義的工藝結(jié)論和建議，有效解決了CAE系統(tǒng)的復(fù)雜性與用戶使用要求的簡(jiǎn)單性之間的矛盾，縮短了CAE系統(tǒng)與用戶之間的距離，將仿真軟件由傳統(tǒng)的“被動(dòng)式”計(jì)算工具提升為“主動(dòng)式”優(yōu)化系統(tǒng)。HSCAE　3D系統(tǒng)主要將人工智能技術(shù)應(yīng)用于初始工藝方案設(shè)計(jì)、CAE分析結(jié)果的解釋和評(píng)價(jià)、分析方案的改進(jìn)與優(yōu)化3個(gè)方面。35
