摘要
本文根据正交各向异性柱壳的基本力学关系,推导了柱壳受纵向拉力和垂直力作用时的应力、应变等变量的关系式。并针对钢绳芯胶带运输机的胶带特点及边界条件,用位移法分析和推导可表示各变量间关系的函数式,并给出了求解整个过程的计算框图。
Based on the general mechanic behaviour of the orthogonal anisotropic casing, its stress, strain and other variation relations due to the action of longitudinal tensile forces and vertical compressive forces are deduced. By the displacement method, functions relating various parameters are derived considering the belt properties and boundary conditions of steel-cord belt conveyors. A calculating block diagram is given for solutions to the whole process
