【摘要】：帶式輸送機(jī)作為現(xiàn)代散裝物料運(yùn)輸?shù)闹匾ぞ咧?近年來(lái)越來(lái)越向著長(zhǎng)距離、高速度、大運(yùn)量的方向發(fā)展。傳統(tǒng)的設(shè)計(jì)方法已經(jīng)無(wú)法滿足現(xiàn)代帶式輸送機(jī)發(fā)展的需要,隨著電子科學(xué)技術(shù)的發(fā)展,現(xiàn)代設(shè)計(jì)方法中的CAD與CAE技術(shù)已經(jīng)越來(lái)越廣泛地應(yīng)用在輸送機(jī)的設(shè)計(jì)中,它大大縮短了設(shè)計(jì)周期、提高了設(shè)計(jì)質(zhì)量、減少了設(shè)計(jì)費(fèi)用。為此,本文借助現(xiàn)代設(shè)計(jì)方法中的CAE技術(shù)對(duì)帶式輸送機(jī)的一些關(guān)鍵技術(shù)做了分析研究。 首先通過(guò)對(duì)帶式輸送機(jī)動(dòng)態(tài)分析設(shè)計(jì)理論的分析,建立了帶式輸送機(jī)輸送帶的數(shù)學(xué)模型。然后利用AMESIM軟件建立了帶式輸送機(jī)動(dòng)態(tài)仿真模型,對(duì)滿載可控啟動(dòng)工況下的帶式輸送機(jī)進(jìn)行了動(dòng)態(tài)仿真。通過(guò)仿真,得出了靠近驅(qū)動(dòng)滾筒機(jī)頭輸送帶與機(jī)尾輸送帶處的張力變化規(guī)律、速度變化規(guī)律、加速度變化規(guī)律以及張緊裝置的位移變化規(guī)律。結(jié)果表明,驅(qū)動(dòng)端輸送帶的動(dòng)張力最大,在整個(gè)輸送帶上是最為危險(xiǎn)的區(qū)域。通過(guò)對(duì)不同的啟動(dòng)時(shí)間F輸送帶的動(dòng)態(tài)特性進(jìn)行分析對(duì)比,發(fā)現(xiàn)輸送帶的動(dòng)態(tài)特性隨著啟動(dòng)時(shí)間的增長(zhǎng)的非線性變化規(guī)律,為輸送機(jī)的動(dòng)力學(xué)分析提供了一種比較直觀與簡(jiǎn)便的方法。 對(duì)驅(qū)動(dòng)滾筒與纏繞在其上的一段輸送帶進(jìn)行理論受力與變形分析,然后運(yùn)用ANSYS軟件建立驅(qū)動(dòng)滾筒與輸送帶摩擦接觸的三維模型,并對(duì)其進(jìn)行有限元分析。首先介紹了有限元法的基本理論和ANSYS軟件分析的全過(guò)程；在ANSYS環(huán)境中,改進(jìn)以往的建模方式,建立了輸送帶和驅(qū)動(dòng)滾筒摩擦接觸的三維模型,使輸送帶在運(yùn)轉(zhuǎn)以前就具有較正確的張力。最后通過(guò)分析ANSYS分析結(jié)果,得出了驅(qū)動(dòng)端輸送帶和驅(qū)動(dòng)滾筒上筒殼、輻板、軸等主要零部件的受力云圖以及變形圖,能夠解決帶式輸送機(jī)驅(qū)動(dòng)滾筒設(shè)計(jì)過(guò)程中的一些實(shí)際問(wèn)題,并為以后滾筒的進(jìn)一步優(yōu)化設(shè)計(jì)提供了新的模型和方法。
[Abstract]:Belt conveyor, as one of the important tools of modern bulk material transportation, is becoming more and more long distance and high speed in recent years. Traditional design methods can not meet the needs of the development of modern belt conveyor, with the development of electronic science and technology. CAD and CAE technology in modern design methods have been more and more widely used in the design of conveyors, which greatly shorten the design cycle, improve the design quality and reduce the design cost. In this paper, some key technologies of belt conveyor are analyzed and studied with the help of CAE technology in modern design method. Firstly, through the analysis of the dynamic analysis and design theory of belt conveyor, the mathematical model of belt conveyor belt is established, and then the dynamic simulation model of belt conveyor is established by using AMESIM software. The dynamic simulation of belt conveyor under the condition of full load controllable start-up is carried out. Through simulation, the law of tension and speed change near the belt of the head of driving roller and the belt of tail are obtained. The results show that the dynamic tension of the conveyor belt at the driving end is the largest. It is the most dangerous area on the whole conveyor belt. By analyzing and comparing the dynamic characteristics of F conveyor belt with different start-up time, it is found that the dynamic characteristics of conveyor belt change with the increase of start-up time. It provides a simple and convenient method for dynamic analysis of conveyer. The theoretical force and deformation of the driving drum and the conveyor belt wound on it are analyzed, and then the three-dimensional model of friction contact between the driving drum and the conveyor belt is established by using ANSYS software. Firstly, the basic theory of finite element method and the whole process of ANSYS software analysis are introduced. In the environment of ANSYS, the three-dimension model of the belt and the friction contact of the driving drum is established by improving the previous modeling method. The conveyor belt has the correct tension before running. Finally, by analyzing the results of ANSYS analysis, the driving end conveyor belt and the upper cylinder shell and radial plate of the driving roller are obtained. The mechanical cloud diagram and deformation diagram of the main parts such as shaft can solve some practical problems in the design process of belt conveyor driving drum and provide a new model and method for the further optimization design of the drum in the future.
