【摘要】：研究承载输送带压陷阻力能耗机理,可以为设计低能耗、高速度、大运量、大功率输送机提供理论依据。通过对运行中输送带与物料间相互作用机理研究,覆盖层采用三元件固体模型,基于平型托辊上输送带压陷阻力能耗理论,推导出承载输送带通过槽形托辊时压陷阻力及压陷阻力系数计算公式,并结合具体输送机技术参数,利用公式和MATLAB软件对几种主要影响因素进行了分析和探讨,结果表明该公式能够正确反映各种因素对压陷阻力系数的影响,可以通过选配合适的输送带黏弹性参数,并结合调整输送带和输送机的结构参数达到降低输送带压陷阻力的目的。
[Abstract]:The study on the mechanism of energy consumption of the bearing conveyer belt pressure resistance can provide a theoretical basis for the design of low energy, high speed, large capacity and high power conveyor. Through the interaction between the belt and the material of the study on the mechanism of operation, covering the three elements of solid model, based on the flat roller conveyor belt sag resistance energy theory, carrying through the conveyor belt trough roller when the pressure resistance and pressure resistance coefficient calculation formula is derived, and combined with concrete conveyor technical parameters. On some influential factors were analyzed and discussed by using formula and MATLAB software, the results show that the formula can reflect the influence of various factors on the pressure resistance coefficient, by selecting the suitable viscoelastic parameters of conveyor belt, and combined with the adjustment of structure parameters of conveyor belt and conveyor to reduce the transmission resistance with pressure to.
