【摘要】：圓管帶式輸送機是在傳統(tǒng)槽形帶式輸送機基礎上發(fā)展起來的一類特種帶式輸送機。它具有物料大傾角封閉輸送、可以空間彎曲布置、雙向輸送方便等優(yōu)點。廣泛應用于水泥、礦山、電力、冶金、垃圾處理等多種工業(yè)領域。在圓管帶式輸送機上述各項優(yōu)點充分體現(xiàn)的同時對圓管帶式輸送機的支承部分(桁架梁和支柱)提出了更高的要求。 由于圓管帶式輸送機的結構比較復雜,如果采用傳統(tǒng)的手工計算方法,勢必會大大增加設計計算工作量,延長設計周期。有限元方法是目前廣泛應用于結構設計領域的一種現(xiàn)代設計計算分析方法,應用ANSYS軟件對結構進行有限元分析是圓管帶式輸送機結構設計的發(fā)展趨勢。因此,研究圓管帶式輸送機的有限元分析中涉及到的模型處理技巧與關鍵問題,并據此開發(fā)一套圓管帶式輸送機參數(shù)化有限元分析系統(tǒng)是十分有意義的。 在研究了圓管帶式輸送機鋼結構的組成和類型的基礎上,確定了圓管帶式輸送機彎曲線路的曲線方程,分析了圓管帶式輸送機鋼結構的特征參數(shù)和載荷形式。對圓管帶式輸送機鋼結構模型進行了合理簡化,利用ANSYS軟件參數(shù)化設計APDL編寫命令流,實現(xiàn)鋼結構參數(shù)化模型的建立。對桁架梁進行了理論計算,將計算結果與ANSYS軟件分析結果對比,確定了ANSYS分析桁架梁結果的合理性。利用ANSYS軟件對圓管帶式輸送機鋼結構進行了靜力學和動力學分析,并對其剛度、強度、進行了校核。以圓管帶式輸送機鋼結構的有限元分析為基礎,應用Visual Basic6.0的界面編程語言和ANSYS中的參數(shù)化設計語言APDL以及Access數(shù)據庫開發(fā)出圓管帶式輸送機鋼結構參數(shù)化有限元分析軟件,并對軟件的開發(fā)方法、功能及使用方法進行了介紹。 本文的研究內容和成果,一方面對提高圓管帶式輸送機的設計效率有較大的使用價值,同時也能為其它類似的參數(shù)化分析系統(tǒng)的開發(fā)提供一種有效的參考。
[Abstract]:Circular tube belt conveyor is a kind of special belt conveyor developed on the basis of traditional groove belt conveyor. It has the advantages of large obliquity closed conveying, space bending arrangement and convenient two-way conveying. Widely used in cement, mining, electric power, metallurgy, garbage treatment and other industrial fields. At the same time, higher requirements are put forward for the supporting part (truss beam and support) of the circular pipe belt conveyor. Because the structure of circular pipe belt conveyor is quite complex, if the traditional manual calculation method is adopted, the workload of design calculation will be greatly increased and the design period will be prolonged. Finite element method is a kind of modern design analysis method which is widely used in the field of structural design at present. It is the development trend of structural design of circular pipe belt conveyor to use ANSYS software to carry out finite element analysis of structure. Therefore, it is very meaningful to study the model processing skills and key problems involved in the finite element analysis of circular pipe belt conveyor, and to develop a parameterized finite element analysis system for circular pipe belt conveyor. On the basis of studying the composition and type of steel structure of tubular belt conveyor, the curve equation of curved line of circular pipe belt conveyor is determined, and the characteristic parameters and load form of steel structure of circular pipe belt conveyor are analyzed. The steel structure model of circular pipe belt conveyor is reasonably simplified, and the command flow is compiled by using ANSYS software parameterized design APDL to realize the establishment of the steel structure parameterized model. The theoretical calculation of the truss beam is carried out. The rationality of the ANSYS analysis of the truss beam is determined by comparing the calculated results with the results of the ANSYS software. The statics and dynamics of steel structure of circular pipe belt conveyor were analyzed by ANSYS software, and its stiffness and strength were checked. Based on the finite element analysis of the steel structure of the circular pipe belt conveyor, the parametric finite element analysis software for the steel structure of the circular pipe belt conveyor is developed by using the interface programming language of Visual Basic6.0, the parametric design language APDL in ANSYS and the Access database. The development method, function and use method of the software are also introduced. The research contents and achievements of this paper are of great practical value for improving the design efficiency of circular pipe belt conveyor, and can also provide an effective reference for the development of other similar parameterized analysis systems.
