【摘要】：运输带在煤炭及矿业产品的运输过程中,起到了至关系重要的作用。相对于火车、汽车、飞机等运输方式而言,运输带运输方式具有运输成本低、效能高、环保等诸多优点,但是仍有其自身不可忽视的问题,如运输带本身重量较重,运输带在长时间输送时会出现断裂以及需要张紧等问题。在这些问题中,运输带本身的自重是最为严重的问题,它不仅降低了承载能力,使运输带寿命缩短,而且更重要的是增加了能源消耗。如果在不降低运输带使用寿命的前提下,降低运输带的自重,就会使运输带承载能力增加、能耗降低,其带来的经济效益将非常可观。为了实现国家确定的节能降耗的目标,各个运输带生产厂家均对自家厂品进行了优化设计和改造,以力求达到市场和客户的要求。本文从模拟和实验角度上,对某公司研发的轻型节能高强力钢丝绳芯运输带进行了研究,具体工作如下：(1)从橡胶的物理性能入手,建立了运输带承载能力的物理和数学模型,构建了重力场,重点研究了运输带的运载机理和承载变形机理的关系。(2)使用有限元ABAQUS软件对新型运输带和传统型运输的带卷曲性能、过弯性能、压陷滚动性能进行了研究。通过应力大小,应力分布,应变大小,位移大小等相关数据的研究,得出了新型运输带的卷曲性能、过弯性能、压陷滚动性能优于传统运输带的结论。(3)通过实验,研究了运输带的卷曲性能、压陷滚动性能,通过所测的应力大小,应力分布,应变大小,位移大小等相关数据,得出了新型运输带的性能优于传统运输带的性能的结论。通过实际应用,新型运输带的单位重量降低了30-50%,承载能力提升20%-25%,能耗减少了15%-20%,输送成本降低了40-45%。由此可见,通过合理结构和配方工艺的设计,降低运输带自重对运输带运输过程中节能降耗,提高效益是很有意义的。
[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.
