【摘要】：某熱電廠Ⅱ期擴(kuò)建1x330MW項(xiàng)目門式刮板取料機(jī),此設(shè)備通常工作在系統(tǒng)干煤棚煤場中,取料機(jī)橫跨煤堆進(jìn)行取料作業(yè)。該設(shè)備初步設(shè)計方案已經(jīng)完成,其基本結(jié)構(gòu)包括柔性側(cè)、剛性側(cè)行走機(jī)構(gòu)、刮板取料機(jī)構(gòu)、取料金屬結(jié)構(gòu)、司機(jī)室、電氣室、導(dǎo)料裝置、潤滑裝置、檢測裝置、限位裝置、動力控制電纜卷筒、灑水裝置、平臺欄桿、電控系統(tǒng)等。接下來的工作需要借助CAE商業(yè)軟件,來計算該設(shè)備金屬結(jié)構(gòu)的設(shè)計是否合理,還存在什么問題,不合理之處提出改進(jìn)方案并進(jìn)行優(yōu)化。由于本項(xiàng)目設(shè)計工作采用Auto CAD軟件,與有限元分析工具不存在數(shù)據(jù)接口,所以我們只能夠根據(jù)廠方提供的圖紙人為手工建立計算模型。本項(xiàng)目主要對該設(shè)備金屬結(jié)構(gòu)的以下幾個方面進(jìn)行計算校核：強(qiáng)度計算及校核、剛度計算及校核、穩(wěn)定性計算及校核以及特殊部件的校核,并提出可行性優(yōu)化建議,優(yōu)化模型并計算。本論文采用有限元方法對設(shè)備金屬結(jié)構(gòu)進(jìn)行靜力分析。 本次分析選用Pro/ENGINEER軟件建模并在該軟件Pro/Mechanica分析環(huán)境中進(jìn)行計算并優(yōu)化。根據(jù)計算結(jié)果,結(jié)合實(shí)際的設(shè)計生產(chǎn)經(jīng)驗(yàn)提出改進(jìn)方案。Pro/ENGINEER軟件的特點(diǎn)是：建模功能強(qiáng)大,建模方便,易學(xué)易用,軟件的思想是全參數(shù)化驅(qū)動和數(shù)據(jù)相關(guān)性,使得模型可修改性強(qiáng)。Pro/ENGINEER軟件“標(biāo)準(zhǔn)”環(huán)境下的幾何模型可以無縫導(dǎo)入Pro/Mechanica分析環(huán)境中,由于具有數(shù)據(jù)相關(guān)性,即使模型幾何在“標(biāo)準(zhǔn)”環(huán)境下改動,導(dǎo)入到Mechanica環(huán)境中定義在改動后幾何的單元不需要重新定義。Pro/Mechanica分析環(huán)境采用P方法形成單元的剛度方程,對于常規(guī)結(jié)構(gòu)靜力分析十分有效,可以大大降低模型簡化的難度和工作量,通過使用其自動檢測連接并定義接觸,使得設(shè)計師可以更加專注于模型細(xì)節(jié)的檢查和處理。PTC軟件的單一數(shù)據(jù)庫功能,能夠更加方便地利用參數(shù)化來改動模型。 本項(xiàng)目是CAE技術(shù)有限元分析方法的優(yōu)勢在實(shí)際指導(dǎo)生產(chǎn)中的體現(xiàn)。CAE——計算機(jī)輔助工程,包括工程和制造業(yè)信息化的所有方面,是以現(xiàn)代計算力學(xué)為基礎(chǔ),計算機(jī)仿真為手段的工程分析技術(shù),是實(shí)現(xiàn)產(chǎn)品現(xiàn)代化設(shè)計的重要技術(shù),工程師創(chuàng)新設(shè)計的重要手段和工具。它是計算機(jī)技術(shù)和現(xiàn)代力學(xué)理論結(jié)合產(chǎn)生并發(fā)展起來的交叉領(lǐng)域,并已經(jīng)發(fā)展成為制造業(yè)和工程領(lǐng)域的最重要的技術(shù)之一。CAE分析的關(guān)鍵是在三維實(shí)體建模的基礎(chǔ)上,從產(chǎn)品的方案設(shè)計階段開始,按照實(shí)際使用條件進(jìn)行仿真和結(jié)構(gòu)分析,按照性能要求進(jìn)行設(shè)計和綜合評價以便從多個設(shè)計方案中選擇最佳方案。通過本項(xiàng)目,能夠更加深刻地理解CAE技術(shù)和有限元方法在實(shí)際生產(chǎn)中的地位和作用。并且,也能夠更加熟悉和更加深刻地理解Pro/ENGINEER軟件的強(qiáng)大功能以及其在CAD/CAE領(lǐng)域中的貢獻(xiàn)。
[Abstract]:In the second phase of a thermal power plant, the gate scraper feeder is extended in the second phase of the 1 x 330MW project. The equipment usually works in the dry coal shed coal yard of the system, and the feeder works across the coal pile. The preliminary design scheme of the equipment has been completed, and its basic structure includes the flexible side. Rigid side walking mechanism, scraper feeding mechanism, material taking metal structure, driver's room, electric room, guide device, lubricating device, detection device, limit device, power control cable reel, sprinkler, platform railing, Electrical control system and so on. The next work needs to use CAE commercial software to calculate whether the design of the metal structure of the equipment is reasonable, and what problems still exist. Because the Auto CAD software is used in the design of the project, there is no data interface with the finite element analysis tool. So we can only manually build the calculation model according to the drawings provided by the factory. This project mainly calculates and verifies the following aspects of the metal structure of the equipment: strength calculation and check, stiffness calculation and check, The stability calculation and verification as well as the verification of special components are put forward, and the feasibility optimization suggestion, optimization model and calculation are put forward. In this paper, the finite element method is used to analyze the static force of the metal structure of the equipment. In this analysis, Pro/ENGINEER software is used to model and calculate and optimize in the Pro/Mechanica analysis environment. According to the calculation results, combined with the actual design and production experience, the improved program. Pro-ENGINEER software is characterized by powerful modeling function and convenient modeling. It is easy to learn and use. The idea of software is full parameterized driving and data correlation, which makes the geometric model under the "standard" environment of Pro-ENGINEER software can be seamlessly imported into the Pro/Mechanica analysis environment because of its data correlation. Even if the model geometry is changed in the "standard" environment, the element defined in the modified Mechanica environment does not need to be redefined. The P method is used to form the stiffness equation of the element, which is very effective for the static analysis of conventional structures. It can greatly reduce the difficulty and workload of model simplification. By using it to automatically detect connections and define contacts, designers can focus more on checking model details and processing the single database function of .PTC software. It is more convenient to use parameterization to modify the model. This project is the embodiment of the advantage of the finite element analysis method of CAE technology in actual production. CAE-Computer-Aided Engineering, including all aspects of engineering and manufacturing informatization, is based on modern computational mechanics. The engineering analysis technology by means of computer simulation is an important technology to realize the modern design of products and an important means and tool for engineers' innovative design. It is a cross field produced and developed by the combination of computer technology and modern mechanics theory. CAE analysis is based on 3D solid modeling, starting from the design stage of the product, simulation and structural analysis are carried out according to the actual use conditions, and the CAE analysis has become one of the most important technologies in the manufacturing and engineering fields, and it has become one of the most important technologies in the field of manufacturing and engineering. Design and comprehensive evaluation according to performance requirements in order to select the best solution from multiple design scenarios. Through this project, the position and role of CAE technology and finite element method in practical production can be better understood. Also more familiar with and more in-depth understanding of the power of Pro/ENGINEER software and its contribution to the field of CAD/CAE.
