In order to obtain such technical data as are required for designing vertical double-belt conveyors, the authors carried out a stress-strain analysis of the double-belts through a non-linear finite element method. In the analysis the conveyor belt is assumed to behave as a membrane.
The main results are as follows;
1) The non-linear finite element model expresses the holding mechanism of the double-belts well.
2) When a particle is held between the belts just on an idler, local tensile stress which is 2 or 3 times larger than the mean value generates in the outer belt.
3) When the belt width is small, the condition that no local loosening should occur in the belts determines the minimum operational tension, while when the belt width is large, the equilibrium of the forces acting on the conveyed materiald etermines it.
