【摘要】：運(yùn)輸帶在煤炭及礦業(yè)產(chǎn)品的運(yùn)輸過(guò)程中,起到了至關(guān)系重要的作用。相對(duì)于火車(chē)、汽車(chē)、飛機(jī)等運(yùn)輸方式而言,運(yùn)輸帶運(yùn)輸方式具有運(yùn)輸成本低、效能高、環(huán)保等諸多優(yōu)點(diǎn),但是仍有其自身不可忽視的問(wèn)題,如運(yùn)輸帶本身重量較重,運(yùn)輸帶在長(zhǎng)時(shí)間輸送時(shí)會(huì)出現(xiàn)斷裂以及需要張緊等問(wèn)題。在這些問(wèn)題中,運(yùn)輸帶本身的自重是最為嚴(yán)重的問(wèn)題,它不僅降低了承載能力,使運(yùn)輸帶壽命縮短,而且更重要的是增加了能源消耗。如果在不降低運(yùn)輸帶使用壽命的前提下,降低運(yùn)輸帶的自重,就會(huì)使運(yùn)輸帶承載能力增加、能耗降低,其帶來(lái)的經(jīng)濟(jì)效益將非�？捎^。為了實(shí)現(xiàn)國(guó)家確定的節(jié)能降耗的目標(biāo),各個(gè)運(yùn)輸帶生產(chǎn)廠家均對(duì)自家廠品進(jìn)行了優(yōu)化設(shè)計(jì)和改造,以力求達(dá)到市場(chǎng)和客戶(hù)的要求。本文從模擬和實(shí)驗(yàn)角度上,對(duì)某公司研發(fā)的輕型節(jié)能高強(qiáng)力鋼絲繩芯運(yùn)輸帶進(jìn)行了研究,具體工作如下：(1)從橡膠的物理性能入手,建立了運(yùn)輸帶承載能力的物理和數(shù)學(xué)模型,構(gòu)建了重力場(chǎng),重點(diǎn)研究了運(yùn)輸帶的運(yùn)載機(jī)理和承載變形機(jī)理的關(guān)系。(2)使用有限元ABAQUS軟件對(duì)新型運(yùn)輸帶和傳統(tǒng)型運(yùn)輸?shù)膸Ь砬阅�、過(guò)彎性能、壓陷滾動(dòng)性能進(jìn)行了研究。通過(guò)應(yīng)力大小,應(yīng)力分布,應(yīng)變大小,位移大小等相關(guān)數(shù)據(jù)的研究,得出了新型運(yùn)輸帶的卷曲性能、過(guò)彎性能、壓陷滾動(dòng)性能優(yōu)于傳統(tǒng)運(yùn)輸帶的結(jié)論。(3)通過(guò)實(shí)驗(yàn),研究了運(yùn)輸帶的卷曲性能、壓陷滾動(dòng)性能,通過(guò)所測(cè)的應(yīng)力大小,應(yīng)力分布,應(yīng)變大小,位移大小等相關(guān)數(shù)據(jù),得出了新型運(yùn)輸帶的性能優(yōu)于傳統(tǒng)運(yùn)輸帶的性能的結(jié)論。通過(guò)實(shí)際應(yīng)用,新型運(yùn)輸帶的單位重量降低了30-50%,承載能力提升20%-25%,能耗減少了15%-20%,輸送成本降低了40-45%。由此可見(jiàn),通過(guò)合理結(jié)構(gòu)和配方工藝的設(shè)計(jì),降低運(yùn)輸帶自重對(duì)運(yùn)輸帶運(yùn)輸過(guò)程中節(jié)能降耗,提高效益是很有意義的。
[Abstract]:Transport belt plays an important role in the transportation of coal and mining products. Compared with train, automobile, aircraft and so on, the transport belt has many advantages, such as low transportation cost, high efficiency, environmental protection and so on. However, it still has its own problems, such as the heavy weight of the belt itself. The transport belt will break and need tension during long-term transportation. Among these problems, the weight of the transport belt itself is the most serious problem. It not only reduces the carrying capacity, shortens the life of the transport belt, but also increases the energy consumption. If the service life of the transport belt is not reduced, the load carrying capacity of the belt will increase and the energy consumption will be reduced, and the economic benefits will be very considerable. In order to achieve the goal of saving energy and reducing consumption, each transport belt manufacturer has optimized the design and transformation of its own products in order to meet the requirements of the market and customers. In this paper, the light energy saving and high strength steel rope core transport belt developed by a company is studied from the point of view of simulation and experiment. The specific work is as follows: (1) starting with the physical properties of rubber, The physical and mathematical models of the carrying capacity of the transport belt are established, and the gravity field is constructed. The relationship between the carrying mechanism and the bearing deformation mechanism of the transport belt is mainly studied. (2) the crimp, overbending and rolling properties of the new transport belt and the traditional transportation are studied by using the finite element ABAQUS software. Based on the research of stress size, stress distribution, strain size, displacement and other related data, it is concluded that the crimp, overbending and rolling performance of the new transport belt are superior to those of the traditional transport belt. (3) through experiments, the conclusion is drawn that the rolling performance of the new transport belt is better than that of the traditional transport belt. The crimp and rolling properties of the transport belt are studied. The performance of the new transport belt is better than that of the traditional transport belt, based on the measured data of stress, stress distribution, strain, displacement and so on. Through practical application, the unit weight of the new transport belt is reduced by 30-50, the carrying capacity is increased by 20 to 25, the energy consumption is reduced by 15 to 20, and the transportation cost is reduced by 40-4550. It can be seen that it is very meaningful to reduce the deadweight of transport belt through the design of reasonable structure and formula technology to save energy and reduce consumption in the transportation process of transport belt and to improve the benefit.
