摘　　要：建立复杂圆管带式输送机的有限元模型,提出长距离管带机悬垂度分析的代表性单元法,并试验研究管带机胶带的力学特性。仿真模拟了管带机在给定张力和物料密度条件下的变形、应力和悬垂度,据此分析托辊间距对悬垂度的影响,并考虑实际的约束条件,确定了某管带机项目的最佳悬垂度。The finite element model for complex pipe conveyor belt was established, a representa-tive element method for belt suspension structure analysis of long distance conveyor belt was pro- posed,and the mechanical properties of rubber compound were experimentally investigated. The de- formation, stress and suspension of the belt under certain tension force and material density were sim- ulated ,which could be used to analyze the effect of roller gap on the belt suspension, and the optimized belt suspension structure could be determined by taking into consideration of the constrained condi- tions.
