【摘要】：隨著現(xiàn)代化發(fā)展的要求,環(huán)保已成為當(dāng)今時(shí)代性的重要問題,并且在世界各個(gè)國家引起了廣泛的重視。正是在這種減少生產(chǎn)污染,提倡環(huán)保和無公害化輸送散裝物料的要求下,管狀帶式輸送機(jī)應(yīng)運(yùn)而生。目前,管狀帶式輸送機(jī)在世界范圍內(nèi),它是一種最先進(jìn)的物料輸送設(shè)備,對管帶機(jī)進(jìn)行機(jī)械結(jié)構(gòu)分析,參數(shù)分析,并利用有限元分析與計(jì)算機(jī)仿真技術(shù)對其深入地分析與研究,對國外先進(jìn)技術(shù)和設(shè)備的消化、吸收、改造提供理論依據(jù),并對實(shí)際生產(chǎn)具有重要的指導(dǎo)意義。 本課題的主要任務(wù)是：對管狀帶式輸送機(jī)的工作原理、特點(diǎn)進(jìn)行介紹并確定部分參數(shù),然后綜合有限元分析方法及其后處理模塊的詳細(xì)介紹,針對傳動(dòng)滾筒及其軸承座等典型機(jī)構(gòu),詳細(xì)介紹了在ANSYS軟件中建立有限元模型過程,模擬現(xiàn)實(shí)工況下的受力情況,進(jìn)行強(qiáng)度校核,分析改進(jìn)后結(jié)構(gòu)的可靠性。 管狀帶式輸送機(jī)傳動(dòng)滾筒及其軸承座的有限元分析結(jié)果表明,現(xiàn)有的傳動(dòng)滾筒機(jī)構(gòu)和軸承座強(qiáng)度依然可靠,達(dá)到了設(shè)計(jì)要求,為管帶機(jī)的進(jìn)一步優(yōu)化設(shè)計(jì)提供了指導(dǎo)作用。 該課題采用有限元分析為基礎(chǔ),建立了力學(xué)模型和數(shù)學(xué)模型,詳細(xì)分析了管帶機(jī)主要零部件機(jī)械結(jié)構(gòu)、力能參數(shù)及其仿真,分析和解決了管帶機(jī)中的傳動(dòng)滾筒及其軸承座的強(qiáng)度分析難點(diǎn)。并且在解決管帶機(jī)中出現(xiàn)的問題所應(yīng)用的理論知識和現(xiàn)代設(shè)計(jì)方法都很有前沿性、先進(jìn)性,且其所得到的結(jié)果都比較準(zhǔn)確,合乎設(shè)計(jì)要求。從而在對本課題的研究和探討,對使用者進(jìn)行管帶機(jī)的研究提供了很大的方便性和參考價(jià)值。
[Abstract]:With the development of modernization, environmental protection has become an important issue of the times, and has attracted extensive attention in various countries of the world. It is in this way to reduce production pollution. Under the requirement of promoting environmental protection and pollution-free transportation of bulk materials, the tubular belt conveyor emerges as the times require. At present, the tubular belt conveyor is the most advanced material conveying equipment in the world. Mechanical structure analysis, parameter analysis, finite element analysis and computer simulation technology are used to analyze and study the pipe belt machine, and digesting and absorbing foreign advanced technology and equipment. The transformation provides the theoretical basis and has the important guiding significance to the actual production. The main task of this subject is to introduce the working principle and characteristics of the tubular belt conveyor and determine some parameters. Then the finite element analysis method and the post-processing module are introduced in detail. Aiming at the typical mechanism such as the transmission roller and its bearing seat, this paper introduces in detail the process of establishing the finite element model in the ANSYS software, simulates the force situation under the actual working condition, and carries on the strength check. The reliability of the improved structure is analyzed. The finite element analysis results of the transmission drum and its bearing seat of the tubular belt conveyor show that the strength of the existing transmission roller mechanism and bearing seat is still reliable and meets the design requirements. It provides the guidance for the further optimization design of the pipe belt machine. Based on the finite element analysis, the mechanical model and mathematical model are established, and the mechanical structure, force and energy parameters and their simulation of the main parts of the pipe belt machine are analyzed in detail. The paper analyzes and solves the difficulty of strength analysis of the transmission drum and its bearing seat in the tube-strip machine, and the theoretical knowledge and modern design method used in solving the problems in the tube-strip machine are very advanced and advanced. The results obtained are all accurate and accord with the design requirements. Therefore, this paper provides a great convenience and reference value for the users to study the pipe and belt machine in the research and discussion of this subject.
