Abstract. The key and the most expensive part of the tubular belt conveyor (TBC) is its belt. Calculation of the belt, rolled up into the shell and made of nonlinear (in terms of deformation)material, is a major obstacle for using analytical methods for calculating the belt stress strain state (SSS), parameters of which can be calculated by numerical methods based on the finite element method; however, these methods have some drawbacks, which are associated with specifying of initial data and analyzing of achieved results, as well as their physical interpretation. A new approach is proposed for simplifying the elastic shell general equations, which takes into consideration particularities of the shell loading. Application of this approach allows reducing the problem to the second-order equation relatively to the moments, obtaining its analytical solution and calculating the SSS parameters. Graphic dependencies on varying loading parameters are demonstrated.
Keywords: tubular belt conveyer, stress-strain state, elastic shell general equations, simplification, analytical solving.
