【摘要】：步進(jìn)梁運輸機(jī)簡稱步進(jìn)梁，主要擔(dān)負(fù)鋼卷運輸任務(wù)，是重要的工藝設(shè)備和運輸裝置。步進(jìn)梁運輸機(jī)在軋鋼設(shè)備中屬于附屬設(shè)備，其好壞對生產(chǎn)效率影響很大，發(fā)揮重要作用。若步進(jìn)梁發(fā)生故障，則處理線須停產(chǎn)，將直接影響鋼卷的產(chǎn)量。即使對于有些處理線有可能采用吊車臨時上卷或卸卷，也難以持久和維持產(chǎn)量。所以在方案階段就要使選型布置和性能參數(shù)盡可能合理，不留后患。 本文以某廠現(xiàn)役步進(jìn)梁為研究對象，將理論分析與有限元分析相結(jié)合對其主要部件進(jìn)行分析計算，以滿足該廠的需求。主要從以下幾個方面對步進(jìn)梁進(jìn)行了系統(tǒng)的研究： 1、用三維軟件SolidWorks對步進(jìn)梁進(jìn)行實體建模。以力學(xué)為基礎(chǔ)對步進(jìn)梁動梁機(jī)構(gòu)的力學(xué)特征進(jìn)行了深入細(xì)致的研究。求解了動梁機(jī)構(gòu)的主要部件在最大承載條件下的受力情況，為有限元求解的加載提供了理論依據(jù)。 2、利用有限元分析軟件ANSYS，對動梁進(jìn)行應(yīng)力分析，得到了各構(gòu)件應(yīng)力及變形的主要數(shù)據(jù)，發(fā)現(xiàn)動梁截面部位最大主應(yīng)力符合材料的許用應(yīng)力，說明其設(shè)計合理；對靜梁部件進(jìn)行穩(wěn)定承載能力分析，得出其最大穩(wěn)定承載力，使該廠根據(jù)實際情況合理運輸鋼卷；分析鋼軌在移動載荷作用下，，移動載荷從一端移動到另一端，得出鋼軌的位移和應(yīng)力響應(yīng)，校核其強(qiáng)度。 3、利用SolidWorks軟件提供的運動學(xué)模塊對步進(jìn)梁動梁機(jī)構(gòu)進(jìn)行運動分析，使其滿足該廠要求。 以上工作能夠使步進(jìn)梁在滿足強(qiáng)度要求的條件下實現(xiàn)連續(xù)作業(yè),該方法合理地分析了步進(jìn)梁的強(qiáng)度問題，為同類產(chǎn)品的研究提供參考。
[Abstract]:Stepping beam conveyer, which is mainly responsible for the task of steel coil transportation, is an important process equipment and transportation device. Stepping beam conveyer belongs to subsidiary equipment in rolling equipment, which has a great influence on production efficiency. Play an important role. In the event of a failure of the stepping beam, the processing line must be shut down, which will directly affect the production of steel coils. Even for some processing lines, it is possible to use a crane to temporarily roll or unroll. It is also difficult to sustain and maintain the output. Therefore, the selection and performance parameters should be as reasonable as possible in the scheme stage. In this paper, the active walking beam of a factory is taken as the research object, and the main components are analyzed and calculated by combining the theoretical analysis with the finite element analysis. In order to meet the needs of the factory, the walking beam is studied systematically from the following aspects: 1. The three-dimensional software SolidWorks is used to model the moving beam. Based on mechanics, the mechanical characteristics of the moving beam mechanism are studied in detail. The main components of the moving beam mechanism are solved in this paper. Under the condition of large load. It provides a theoretical basis for the loading of finite element solution. 2. By using finite element analysis software ANSYS, the main data of the stress and deformation of the moving beam are obtained, and it is found that the maximum principal stress in the section of the moving beam accords with the allowable stress of the material. It shows that the design is reasonable; The stable bearing capacity of static beam components is analyzed and the maximum stable bearing capacity is obtained so that the steel coil can be transported reasonably by the factory according to the actual situation. Under the action of moving load, the moving load is moved from one end to the other, and the displacement and stress response of rail is obtained, and its strength is checked. 3. The kinematics module provided by SolidWorks software is used to analyze the kinematics of moving beam mechanism of walking beam, so that it can meet the requirements of the factory. The above work can make the walking beam realize continuous operation under the condition of meeting the strength requirement. This method reasonably analyzes the strength problem of the walking beam and provides a reference for the research of the similar products.
