摘要
带式输送机是散粒物料运输的主要设备,它广泛用于港口、化工、矿山、电站和冶金等工业领域。皮带撕裂事故时有发生,价值数十万元甚至上百万元的输送皮带,一旦发生撕裂事故,在几分钟内就会全部毁坏,造成巨大的经济损失。随着皮带输送机的应用的范围越来越广,其使用量越来越大,发生撕裂的事故也越来越多。因此,进行皮带撕裂特征的研究具有很重要的理论意义和实际意义。
     本篇论文从弹性动力学理论、输送机皮带撕裂过程的计算机仿真、皮带撕裂前后受力与变形特征等几个方面进行了研究,本文的研究工作归纳如下:
     (1)在大量调研基础上,研究了皮带撕裂主要原因,撕裂部位,裂口形式等。
     (2)本文运用弹性动力学理论对输送机非稳定状态下输送带的受力情况做了详细的说明;应用有限元理论建立输送机的皮带撕裂模型;并运用MATLAB软件对输送机的皮带撕裂机理进行了动态模拟,通过实例,分析带式输送机起、制动动态模拟结果。
     (3)研究了皮带纵向撕裂前后受力与变形特征,即研究皮带张紧力和皮带自身重量、承载物料的重量的变化对皮带撕裂前后产生的横向纵向应力分布及横向纵向变形,找出了其显著特征。
     (4)分析了皮带撕裂过程中的信号检测,进行了皮带撕裂检测方案的应用研究。
Belt conveyor is the main device of modern scattered material successive transportation; it's widely used in industrial domains as harbor transport, chemical industry, mines, power plant and metallurgy. It is unenviable that the belt tear accident happens occasionally, when it happens, the belt will destroy within several minutes, causing hundreds of thousands dollars loss on itself value, or even more economic loss. With the conveyor belt of an increasingly wide range use, the tear incident occurs more frequently. Thus, it is important to study the characteristics of the belt tear theoretical and practical significance.
     This paper studies on the computer simulation of tear process based on the kinetic theory of elasticity, tear stress and deformation character rounded by several aspects. This research is summarized as follows;
     (1) Based on the large number of investigations, mainly because of torn belt, torn parts points format.
     (2) This paper particularly explain the force on the belt in unsteady predicament, and put up breaking principle dynamics simulate experiment with MATLAB software, analyzing the results of start and brake dynamical simulation.
     (3) Studies on the vertical belt around by the tear strength and deformation character study their own weight belt tensioning and belt. Bearing the weight of the material around a set of changes to the belt and empty tear of the lateral vertical and horizontal-vertical stress distribution Deformation identified notable features.
     (4)This paper has analyzed signal detection in the course of Belt tearing, has carried on the research of the Control system of the belt conveyer.
