CALCULATION OF THE SYSTEM OF TWO CLOSED CYLINDRICAL SHELLS WITH INTERMEDIATE SUPPORT

Abstract


A spatial system of two closed cylindrical shells is considered, having rigid fixation at one end and a free end at the other. Shells are located at some distance from each other and are interconnected by one intermediate link. One of the shells is under the action of a load, concentrated in the annular direction and uniformly distributed along one generatrix. To cal- culate the spatial system, the force method is used. Thus, the calculation of the spatial system is reduced to the calculation of individual closed cylindrical shells. From the condition of equality of radial displacements at the point of contact of the shells, the reactive pressure in the intermediate bond was determined. The magnitude of the reactive pressure in the bond varies depending on the location of the intermediate bond and the geometric parameters of the shells. Knowing the magnitude of the reactive pressure, one can determine the stress-strain state of each shell
