采用有限元分析方法,研究了带式输送机的结构和工作情况。运用ANSYS软件建立了带式输送机机架的三维计算模型,并对其结构进行计算,求出了机架在载荷作用下的最大变形和最大应力及变形和应力所处的位置。根据计算结果提出了机架结构设计改进方案,并对改进后的结构进行了分析。结果表明,改进后经济效益显著。 Finite element analysis method is used to study the structure and working condition of belt conveyor. The three-dimensional calculation model of the belt conveyor frame is established by ANSYS software. The structure is calculated and the maximum deformation, the maximum stress and the location of the deformation and stress of the frame under the load are obtained. According to the result of the calculation, an improved scheme of frame structure design is put forward, and the improved structure is analyzed. The results show that after the improvement of economic benefits significantly.
