【摘要】：隨著工業(yè)技術的迅速發(fā)展,振動給料斗作為新型破拱給料設備——活化給料機的核心,由于其具有結構簡單、安裝操作容易、運行可靠、給料連續(xù)均勻、破拱能力強等優(yōu)點,在煤炭、化工、冶金等行業(yè)中得到了廣泛的應用。但活化給料機運行過程中自身零部件結構設計是否合理對給料性能有很大的影響,因此對其動力學建模分析與參數(shù)優(yōu)化研究具有重要的理論意義和實際應用價值。 本論文在借鑒相關給料機設計的基礎上設計了一套全新的振動給料系統(tǒng)。經(jīng)過全新設計后在往皮帶傳送機上裝卸物料時消除了物料飛濺的現(xiàn)象,顯著提高了大型物料堆場的輸送效率,具有實際的應用價值。所取得的研究成果在國內(nèi)外的煤炭行業(yè)中加以推廣應用,必將會帶來直接的經(jīng)濟效益和社會效益。本文以平面范疇內(nèi)運動的慣性平旋型橢圓活化給料機系統(tǒng)為例,著重研究了給料系統(tǒng)中振動給料斗的動力學建模、動力學計算分析以及優(yōu)化設計等問題。 本文首先建立了活化給料機系統(tǒng)的動力學模型,將其簡化為彈簧—質(zhì)量系統(tǒng),在深入研究活化給料機工作原理的基礎上,從理論上去展開活化給料機系統(tǒng)的動力學特性的研究工作,包括建立其系統(tǒng)的振動方程以及相關理論數(shù)據(jù)的計算。 其次,在相關理論數(shù)據(jù)計算的基礎上,基于三維建模軟件Pro/E進行活化給料機的三維建模工作,再借助于有限元分析軟件ANSYS研究活化給料機系統(tǒng)復雜的動力學特性,掌握其固有特性及動力學響應。 然后,在物料的運動過程中建立活化給料機的動力學模型,建立物料運動過程中振動系統(tǒng)的動力學方程,研究其動力學特性以及在給料過程中影響給料性能的參數(shù),供后續(xù)章節(jié)的參數(shù)優(yōu)化分析使用。 最后,基于仿真優(yōu)化軟件MATLAB對活化給料機進行相應的參數(shù)優(yōu)化設計,對原有的設計參數(shù)進行相應的改善并得出組合最合理的設計參數(shù),使其給料性能更加完善。
[Abstract]:With the rapid development of industrial technology, the vibrating feed hopper is the core of the new type of broken arch feeder, which has the advantages of simple structure, easy installation and operation, reliable operation, uniform feeding, strong ability of breaking arch, etc. However, whether the structural design of its components is reasonable or not has a great influence on the feed performance during the operation of the activated feeder. Therefore, it is of great theoretical significance and practical application value to study the dynamic modeling and parameter optimization of the activated feeder. After the new design, the splashing phenomenon is eliminated when loading and unloading the material on the belt conveyer, and the conveying efficiency of the large material yard is improved obviously, which has practical application value. The research results obtained in the coal industry at home and abroad will be popularized and applied, which will bring direct economic and social benefits. Taking the inertial flat rotation elliptical activated feeder system as an example, the dynamic modeling, dynamic calculation and analysis and optimization design of the vibrating hopper in the feed system are studied in this paper. In this paper, the dynamic model of the activated feeder system is established, which is simplified as a spring-mass system. On the basis of in-depth study of the working principle of the activated feeder, The research work on the dynamic characteristics of the activated feeder system is carried out theoretically, including the establishment of the vibration equation of the system and the calculation of the related theoretical data. Secondly, on the basis of the relevant theoretical data calculation, the 3D modeling work of activated feeder is carried out based on the 3D modeling software Pro/E, and the complex dynamic characteristics of the activated feeder system are studied by means of the finite element analysis software ANSYS. Master its inherent characteristics and dynamic response. Then, the dynamic model of activated feeder is established in the process of material movement, and the dynamic equation of vibration system in the process of material movement is established. The dynamic characteristics of the system and the parameters that affect the feed performance in the process of feeding are studied. For parameter optimization analysis in subsequent chapters. Finally, based on the simulation optimization software MATLAB, the parameters of the activated feeder are optimized, the original design parameters are improved and the most reasonable design parameters are obtained, which makes the feed performance more perfect.
